X=2 because it equals 12.
The solution to this equation is in the picture i’ve put below!
the line is negative because it goes down as you move right
slope = rise/run = 4/2 = 2
y = 2x+b
use a point on the line - I picked (-4, 3)
3 = 2(-4)+b
3 = -8+b
11 = b
<h2>
y = 2x +11</h2>
The coordinates would be multiplied by 3, as the scale factor is 3, and it is a dilation, so we know the size increases.
