Question

What is the y-intercept of the equation of the line that is perpendicular to the line y = -3/5x + 10 and passes through the point (15, –5)? The equation of the line in slope-intercept form is y =-5/3 x +

Answer 1

No. The slope would be 5/3 because u flip the numbers AND the sign.
So then -5=5/3(15) + b
-5=25+b
-30=b
y = 5/3x - 30
