Answer:
x y
0 0 - this is the y intercept
1 -4
2 -8
3 -12
4 -16
Step-by-step explanation:
2x = 3
x = 3/2 or 1 1/2 or 1.5
We call x the 4 points-worth problems and y the 3 points-worth problems
You know that x+y = 32
4x+3y = 111
You know that the difference from the x and y is 32 so write:
x = 32-y
Substitute at x the value of 32-y
4(32-y)+3y = 111
128-4y +3y = 111
-4y+3y = 111-128
-y = -17
y = 17
