help pls

[drowsy hazel]

to work out the gradient (m)

use distance up/distance across

so what u wanna do is mark two points on the line and form a triangle, then work out m

@cinder sonnet

[cinder sonnet]

thats what i did-

[drowsy hazel]

lets see

[drowsy hazel]

did u put 1/2?

[cinder sonnet]

why 1???

[drowsy hazel]

simplified verison of 2/4

what did u put?

[cinder sonnet]

0.5

[drowsy hazel]

its a negative gradient

if u look at the line, u will notice why

[cinder sonnet]

yes

but

so

im confused

i did rise over run

2/4

which was 0.5-

[drowsy hazel]

its -0.5 in this case

because the line isnt going up

[cinder sonnet]

OHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

ok

[drowsy hazel]

yep

just be careful when answering these questions

[cinder sonnet]

ive re did this task 3 times-

im also confused at this

[drowsy hazel]

u can use a table

x and y table

so substitute all the values from -1 to 4 in line equation y = 2x - 3

e.g. y = 2(-1) - 3

[cinder sonnet]

yes but like the points?

It moves

so im confused what points it goes on

[drowsy hazel]

have u worked out the y values yet?

[cinder sonnet]

did that as it was last question

[drowsy hazel]

use that

[cinder sonnet]

Im confused-

[drowsy hazel]

plot those points

simple!

[cinder sonnet]

is that correct???

[drowsy hazel]

i cant rlly see

[drowsy hazel]

as long as u plotted the points from this question, u should be good
