Question

johnweldon1993 · Answer

So what are we doing? putting this into y = mx + b form?

anonymous · Answer

yeah so i have to have 3 solutions and all need a line

anonymous · Answer

on a graph and i cant graph a fraction or decmail it has to be a whole number

johnweldon1993 · Answer

Oh okay...well you know that this is a linear equation (straight line) then when you have your 3 points...you can connect them...and hmm whole numbers...okay gimme 1 second :)

Okay 1 point...what does y equal when x = -2?

2nd point...what does y equal when x = 2?

anonymous · Answer

point one 7 
point two 4

johnweldon1993 · Answer

-4y=-5x-18

Point 1 (x = -2)

-4y=-5(-2) -18
-4y = 10 - 18
-4y = -8
y = 2

so 1 point will be (-2 , 2)

Point 2 (x = 2)

-4y=-5(2) -18
-4y = -10 - 18
-4y = -28
y = 7

so another point will be (2 , 7)

And now Point 3 (x = -6)

-4y=-5(-6)-18
-4y = 30 - 18
-4y = 12
y = -3

so your third point will be (-6 , -3)

Just plot those and then draw your straight line :)

anonymous · Answer

yuppers :)

johnweldon1993 · Answer

Alright....so what does 'y' equal when x = 1?

what does 'y' equal when x = 3?

and what does 'y' equal when x = 5?

anonymous · Answer

point 1 is 7 
point 2 is 10
point 3 is 13 ... but my graph doesnt go over ten so will it have to be a negitive??

johnweldon1993 · Answer

Okay no problem...so keep the first 2 points and answer

what does 'y' equal when x = -1?

anonymous · Answer

4

johnweldon1993 · Answer

Perfect!

So your 3 points are

(-1 , 4)

and
(3 , 10)

So plot those and draw your line :)
