linear function

[elder hawk]

is this y=mx+b / ax+by+c=0 stuff?

[lofty talon]

these things

[elder hawk]

translate?

[lofty talon]

in 1st it says sketch the graph of the function and find its slope and y-intercept

[elder hawk]

you know how to sketch a graph?

[lofty talon]

yeah but i dont really know what's this x and y

[elder hawk]

x is the horizontal axis, y is the vertical axis

for each part of the question, its saying that for each x coordinate, the y coordinate is the result of putting the x value into that equation

so if you take part a

f(x)=-3x-3

when x is 1, y is -3(1)-3

go copy from desmos

As a helper, please do not give out answers that could be copied as a homework solution. Have the student work through the problem themselves and guide them along the way.

[rich lava]

so for the first qution

do kwon what is a function

[lofty talon]

not really

i just dont know what to do with that f(x) -3x-3

i know that i have to draw something

[unique kayak]

a line is y = mx + c right

so m is the gradient which is rise/run

so the numerator for rise is -3 and run is 1

means u go down three times and go right once

bc -3 is negative so u go down

so y intercept is -3

graph that point

and then from that point go down 3 times and go right once

then connect those points together x

connect all those points and then ur done uve sketched the graph

Just graph the y intercept and then do the gradient from there

[cursive sluice]

its asking for inverse function?
