Answer:

y=9-1.25x

Explanation:

Start with:

10x+8y=72

We are converting to slope intercept form, meaning we solve for y

Subtract 10x from both sides:

$1.\hspace{10}10x+8y=72\\2.-10x\hspace{23} -10x\\3.\hspace{10}8y=72-10x$

Divide both sides by 8 to isolate y:

$(8y)/(8) =(72)/(8) (-10x)/(8)\\y=9-(10)/(8)x$

Simplify x coefficient:

$y=9-(10)/(8)x\\y=9-(5)/(4)x\\y=9-1.25x$
