Point-Slope Form
Point - Slope Form
y - y1 = m (x - x1)
m = slope
( x1, y1) -- ordered pair
Write an equation in point-slope form of the line that passes through the given point with the given slope.
1. (- 1, 4) m = - 2
Write an equation in point-slope form of the line that passes through the given point with the given slope.
2. (3, - 8) m = ⅔
Write an equation in point-slope form of the line that passes through the given point with the given slope.
3. (4, 7) m = ¾
Write an equation in point-slope form of the line that passes through the given point with the given slope.
4. (5, - 3) m = - 1
