Pls solve fast pls pls pls pls

The answer is a. y = 2z - 3

Step-by-step explanation:

Find the y-intercept.

             -3 is the y-intercept.

Then you do y2 - y1   over x2 - x1

1 - - 1   /  2 - 1

= 2/1

= 2

y = 2z - 3

Hope I helped ya.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
