when you get this kind of exercise, you just need to check which equations resemble the graph

A. y= 6-4x

y= -4x+6

B. y= -4x+8-2

y= -4x+6

C. y= -4x-8-1

y= -4x-9

D. y= -4x+6

-> A, B and D are the same equations

-> the easiest way to find which graph is correct (A/B/D OR C), is to create the graph yourself using the drawn graph:

y= ax+b

a= negative (the line goes down)

to find the a you go 1 step to the left and look which point of the graph has the same x. in this exercise it's when y=4


b= the y-coordinate of the point where the graph cuts the y-axis.


-> graph shown in picture is y= -4x+b

-> graph A/B/D is correct

-> C is does not represent this line
