Question

Find the equation of the line that contains P (-1,3) and is perpendicular to the line that contains
A (-2,0) and B (4,3)

Answer 1

Start by using the points of the second line to find its slope.

Use that slope and point P to find the intercept. This will yield the full equation of the line.

Answer 2

Slope = rise/run = \[\Delta y / \Delta x\] = 3/6 = 0.5

3 = 0.5 (-1) + intercept

3=-0.5 + intercept

intercept = 3+0.5 = 3.5

therefore the equation would be

y=0.5x+3.5
