Determine whether lines through points with given coordinates are parallel or perpendicular

Question

Write an equation that describes the line that passes through the point      (7, – 2) and is perpendicular to the
graph of y = -1/2 x + 1/4

Answer 1

Chris, perpendicular lines have opposite, reciprocal slopes.

 

y - (-2) = 2(x - 7)

y + 2 = 2x - 14

y = 2x - 16
