Write the equation of the line that is perpendicular to the graph of y= 1/2x+6 , and whose y-intercept is (0, -2).

Answer 1

The given line is in the form y = mx + b, so the slope (m) is 1/2. The perpendicular line will then have a slope of -2 (the negative inverse of 1/2)

This gives us y = -2x + b

To find b, plug in the x and y values for the given point, and solve for b
