Question

What is the equation of the line that is perpendicular to the line y=1/2x+7 and passes through the point, (3,-4). What will the slope be?

Answer 1

The equation of the line would be y=–2x+2.

To find the line that is perpendicular to y=1/2x+7, flip both the fraction and sign of the gradient 1/2 from the line.

To find the y-intercept, use the equation:

y=mx+c

Where you input the x and y values from the given coordinates, (3,-4).
