Question

Write the equation of the line that is perpndicular to the line y = -2x -4 and passes through the point (1, -3)

Answer 1

When finding a perpendicular equation you use the negative reciprocal of the slope

Answer 2

So do you know the slope?

Answer 3

-2x

Answer 4

Well that's the original.. but the perpendicular slope is 1/2

Answer 5

oh

Answer 6

so use y-y1=m(x-x1)

Answer 7

y-(-3) = 1/2(x-1)

Answer 8

Correct! Now simplify it and write the final equation

Answer 9

0= 1/2x -3 1/2
