Answer:
1. 32, 12
2. Enlargement
Step-by-step explanation:
Enlarged by a scale factor of 4
(Multiply all points by 4)
8 x 4 = 32
3 x 4 = 12
It is an enlargement because the points are larger than before.

Hey there! :) 
Please keep in mind that slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept
Using this, we can isolate y in our original given equation.
12x - y = 4
Start off by subtracting 12x from both sides.
-y = -12x + 4
Divide both sides by -1.
-y ÷ -1 = (-12x + 4) ÷ -1
Simplify! 
y = 12x - 4 
Therefore, using the slope-intercept form, we can come to the conclusion that because 12 is located in the "m" slot and "m=slope" then 12 is our slope. In addition, -4 is our y-intercept because it is located on the y position. 
Slope = 12 
Y-intercept = -4
