Answer:
160
Step-by-step explanation:
N * 0.7 = 112
N =
you substitute x for 4 and so you multiply 9 x 4 which will give you 36 and then you have to add four times y so you substitute y for -3 and you add 36 - 12 which will give you 24
y-intercept is at (0, 5) for y = 5
for y = 5 is a horizontal line
points (2,3) and (-2,9)
