Question

A linear function goes through the points (-3,1) and (1,-3). What are the coordinates for the y-intercept of this function?

Answer 1

Answer: -2

Explanation:

change in y/ change in x.

-4/4 ---> slope is -1

plug x and y coordinates AND SLOPE into y=mx+b

-3= -4/4(1)+b

-3= -1 +b

-2=b
