Question

Write the equation of the line through (-7,6) and perpendicular to 2x - 10y= 15.​

Answer 1

2x-10y=15.

solve for y to find slope by subtracting 2x from both sides and dividing by -10

y=1/5 x - 3/2

slope = 1/5.

perpendicular slope =-5

y=-5x +b

plug in (-7,6)

6=-5(-7)+b

6=35+b

b=-29

equation is y=-5x-29
