All you have to do is take a quick look at the x-axis (your input values for x in the equation), plug in five x-values within that domain, and then plot that x and y coordinate

solemn prairie Jan 25, 2026, 1:44 AM

#

How 😭

odd scroll Jan 25, 2026, 1:45 AM

#

Make a table

#

Lemme show you

#

Here's an example

#

This is a linear equation tho

#

Do it similarly for your eqn

How do u get the x and ys

odd scroll Jan 25, 2026, 1:47 AM

#

solemn prairie How do u get the x and ys

Js put random values in x and find the value of y or vice versa

#

Then put the respective x and y values in a table like that

solemn prairie Jan 25, 2026, 1:47 AM

#

How do you get the x intercepts 😭

odd scroll Jan 25, 2026, 1:48 AM

#

What

weak scroll Jan 25, 2026, 1:48 AM

#

Set the function equal to 0

#

Solve for all possible x values

odd scroll Jan 25, 2026, 1:48 AM

#

odd scroll Here's an example

Here if i take x=0
The value of y will be -5

solemn prairie Jan 25, 2026, 1:48 AM

#

Ok but how did they get those values

odd scroll Jan 25, 2026, 1:49 AM

#

solemn prairie Ok but how did they get those values

We randomize tho

#

We did it

#

We take an arbitrary value

solemn prairie Jan 25, 2026, 1:49 AM

#

weak scroll Set the function equal to 0

Ok

odd scroll Jan 25, 2026, 1:49 AM

#

Don't take a big number
Since it would result in a hectic calculation

#

@solemn prairie

#

Like this see

#

For example here (x,y)=(3,8)
Hence we plot that point

#

Where x is the value of x taken
And y is value of y found

#

😭

#

@solemn prairie

solemn prairie Jan 25, 2026, 1:57 AM

#

Do you solve for x

#

odd scroll Jan 25, 2026, 2:03 AM

#

You just found out the value of x

#

So

#

When y=0
X=-4.75

#

So plot the point (-4.75,0)

#

@solemn prairie

solemn prairie Jan 25, 2026, 2:06 AM

#

Ok

odd scroll Jan 25, 2026, 2:06 AM

#

solemn prairie Do you solve for x

Yes you could solve either y or x

#

I found solving y easier hence I reccomended that

Dam u pinging me over every sentence lol

solemn prairie Dam u pinging me over every sentence lol

"For whenever u respond to this pls ping me"
You typed this so I made it sure 😭😭😭

solemn prairie Jan 25, 2026, 2:07 AM

#

Lol its ok

#

I dont mind anyways

odd scroll Jan 25, 2026, 2:08 AM

#

Ok 😭

solemn prairie Jan 25, 2026, 2:08 AM

#

It wont let me plot -4.75

#

Only 4 and 5

weak scroll Jan 25, 2026, 2:09 AM

#

That's cause it's allowing only integer values

#

Whole numbers

solemn prairie Jan 25, 2026, 2:10 AM

#

Oh

#

So what do i do

odd scroll Jan 25, 2026, 2:10 AM

#

Yea, adjust and find appropriate values

weak scroll Jan 25, 2026, 2:10 AM

#

Exactly

odd scroll Jan 25, 2026, 2:10 AM

#

Adjust the values

solemn prairie Jan 25, 2026, 2:10 AM

#

Wdym adjust

weak scroll Jan 25, 2026, 2:10 AM

#

Just plug in numbers like -2, 0, 4, 6

solemn prairie Jan 25, 2026, 2:10 AM

#

Into the equation?

weak scroll Jan 25, 2026, 2:11 AM

#

Yeah

#

Then plot those x and y values

solemn prairie Jan 25, 2026, 2:11 AM

#

So how did u know which values to plug in

odd scroll Jan 25, 2026, 2:11 AM

#

Put an arbitrary value of x instead of y

#

I think that would help

#

Like

solemn prairie Jan 25, 2026, 2:12 AM

#

Whats arbitrary

weak scroll Jan 25, 2026, 2:12 AM

#

because it's asking for integer (whole number) values.
it says they must be on the domain given on that x-axis. It must be within that domain

solemn prairie Jan 25, 2026, 2:12 AM

#

So any number just plug it in for x

odd scroll Jan 25, 2026, 2:12 AM

#

X=2
Y=-2*3 +3
Y=-3

odd scroll Jan 25, 2026, 2:13 AM

#

solemn prairie So any number just plug it in for x

No just any number

#

Check that x+7 should be a perfect square

#

Like 2

#

2+7=9

solemn prairie Jan 25, 2026, 2:13 AM

#

So i need to pick number that would make it into a perfect square?

odd scroll Jan 25, 2026, 2:14 AM

#

solemn prairie So i need to pick number that would make it into a perfect square?

Yes

#

That would result in an integer value

solemn prairie Jan 25, 2026, 2:14 AM

#

And then i would solve for y

odd scroll Jan 25, 2026, 2:14 AM

#

solemn prairie And then i would solve for y

Yes

#

Then plot the values in the form (x,y)

solemn prairie Jan 25, 2026, 2:15 AM

#

Okok

#

#

Idk if im doing this right 😭

#

Do i do -2(3)?

#

#

Like this?

odd scroll Jan 25, 2026, 2:23 AM

#

Yea ok

#

Yea you're doing it right

#

So plot (2,-3)

odd scroll Jan 25, 2026, 9:41 AM
