What scale factor is shown in the graph?

a.) 2
b.) -1/2
c.) -2
d.) 1/2

D

Step-by-step explanation:

If you put the points T and T', For T it is -2,4 and for T' it is -1, 2 which is 1/2 of The original. If you di the same for the others you'll see the same thing

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
