B -33
C -45

Answer 2

Answer 3

is it A

Answer 4

Since it's a linear function, you can find the function using y=mx+b where m is the slope and b is the y-intercept. Then you plug in for x.

Answer 5

then whats my answer?

Answer 6

its either a or c

Answer 7

m=(y-y1)/(x-x1)
m=(-21-(-17))/(2-1)
m=(-21+17)/(2-1)
m=(-4)/(1)
m=-4

(y-y1)=m(x-x1)
(y-(-17))=m(x-1)
y+17=-4(x-1)
y+17=-4x+4

y=-4x-13

Answer 8

now, plug in 7 for x, and solve for y
