Answer 1

Hi Aaliyah H.

If your question is if the largest number on the graph is 9 or why the largest number on the graph is 9 you can

Put your line in Slope Intercept Form y = mx + b

9x + 15y = 45

To get this in Slope Intercept Form set up the equation to solve for y in terms of x

15y = -9x + 45

Divide both sides of the equation by 15

y = (-9/15)x + 45/15

y = (-3/5)x + 3

You can graph this line at Desmos.com to confirm whether the largest number on the graph is or is not 9 and why

Give it a try.
