y=-5/6x+15

Explanation:

5x+6y=90

Subtract 5x from both sides of the equation.

6y=90-5x

Divide both sides by 6.

y=90/6-5/6x

Simplify 90/6 to 15.

y=15-5/6x

Rearrange terms on right side.

y=-5/6x+15

This the slope-intercept form of a linear equation y=mx+b, where m is the slope -5/6 and b is the y-intercept 15.
