y=4/3x +38/3

1) For perpendicular lines they have reciprocal slopes multiplied by -1

So our new equation is going to have a slope of m =4/3 in comparison to m=-3/4 from y=-3/4x-2​

2) Writing the slope-intercept form equation:

y=mx+b

y=4/3x+b Plugging into the point

6=4/3(-5) +b

6=-20/3 +b Flipping it

b-20/3=6

b=6+20/3 Calculating the LCM of 1 and 3 and simplifying

b=38/3

y=4/3x +38/3 That's the perpendicular line to the y=-3/4x-2.
