The slope of the given line is -5/3, so a line perpendicular to it will have a slope of 3/5.

Using the slope intercept formula, y = mx + b, your new line will have the equation 8 = (3/5)*(-3) + b.

Solving for b, we get 8 = -9/5 + b

8 + 9/5 = b

40/5 + 9/5 = b

49/5 = b

Your equation is y = 3/5x + 49/5
