Joan looks at yhe graph and says the number of steps is always 3 times the number of feet. is she correct

Step-by-step explanation:

Could you please show us the graph so we could answer as correct as possible? Thanks!

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10
