Question

Determine the y-intercept

Answer 1

-21

Explanation:

the y intercept is when x=0.

you can see that this is a linear equation where each increase in x results in an increase of 4 onto the y value.

so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.

-17 -4=-21

good luck :)
