Question

graph 8x + 9y = 72
just need steps, no graph...medal will be awarded

Answer 1

This is a linear function. Then you need 2 points to draw graph

For easier, 1 point is x = 0, y = 8, and the other point is y = 0, x = 9.

Then connect 2 points so you have the graph

Answer 2

why does x equal zero and y equal 8?

Answer 3

Substitute x = 0 into the equation, then 9y = 72 --> y = 8
