Question

If a graph of y=-9x+ 3 were changed to a graph of y=-9x + 1, how would the
y-intercept change?

Answer 1

Hello!

Answer: y-intercept decreased by 2 points because 3-1=2

I hope I was of help. If not, please let me know! Thanks!

Explanation:

Answer 2

y-intercept decreased by 3-1= 2 points

Explanation:

y=-9x+ 3 ⇒ y-intercept= 3

y=-9x + 1 ⇒ y-intercept= 1

y-intercept decreased by 3-1= 2 points = the line shifted down by 2 points
