Question

Thelma wants to find the equation of a line that passes through the point (2, 2) and is perpendicular to the line y=1/2x+5. What is the equation?

Answer 1

use this equation:
\[y-y_{1}=m(x-x_{1})\]
Plug in your known values. m=-2, since the perpendicular slope is the negative reciprocal of the original slope. You get:
\[y-2 = -2(x-2)\]
Solve for y:
\[y = -2x+6\]

Answer 2

thanks....i will have this yet!
