Question

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (-1, 2).

Answer 1

y = 2x + 4

y = - 2x + 2

y = - 1 over 2 x + 2

y = 2x - 1

Answer 2

First you need to find the slope. And use the given point and the slope to determain the required equation.
To find the slope use the formula m1m2=-1
