(-3, 6); m = 1/2

(1, 0) & (-5, 3)

Write the equation of the line perpendicular to 4x – 5y = -10 through the point(2, 3). Write the equation in slope intercept form.

**Damon**, Wednesday, January 8, 2014 at 5:13pmI am not doing the first line fits because they are the same method as I did for you a few minutes ago.

now

4 x - 5 y = -10

put that in slope intercept form to find the slope

5 y = 4 x + 10

y = (4/5) x + 2

slope = (4/5)

slope of perpendicular = -1/(4/5) = -5/4

so

y = -(5/4) x + b

3 = -(5/4)(2) + b

b = 6/2 + 5/2

b = 11/2

so

y = (-5/4) x + 11/2
