The point-slope form of the equation for a line with slope m
which passes through the point (x 1 ; y 1)
y - y 1 = m (x - x 1)
1. Find the slope and a point on the line whose equation is .
2. Find an equation of the line which passes through the
points (2, -5) and (-1, 3).
Nonvertical parallel lines have the same slope.
1. Find an equation for the line parallel to 2x - 3y = 5 which
passes through the point (2, 1).
2. Are the lines 5x - 2y = 4 and 15x = 6y + 3 parallel or not?
