Today’s Objective To be able to write an equation of a line given two points on the line. Point-Slope (y - y1) = m (x - x1)

1.) Write an equation of a line given The points (1,6) & (3,-4) 1.) Find the Slope m = (-4 -6)/(3-1) m = -10/2 = -5

Write an equation of a line given The points (1,6) & (3,-4) 2.) Plug in one of the points (y - y1) = m(x - x1) (y - 6) = -5(x - 1) y - 6 = -5x + 5

Write an equation of a line given y - 6 = -5x + 5 y - 6 + 6 = -5x + 5 + 6 y = -5x + 11

2.) Write the equation of the line (4,3) Y X (-2,-3)

Write an equation of a line given The points (4,3) & (-2,-3) 1.) Find the Slope m = (-3 -3)/(-2-4) m = -6/-6 = 1

Write an equation of a line given The points (4,3) & (-2,-3) 2.) Plug in one of the points (y - y1) = m(x - x1) (y - 3) = 1(x - 4) y - 3 = 1x - 4

Write an equation of a line given y - 3 = 1x - 4 y - 3 + 3 = x - 4 + 3 y = x - 1

Write an equation of a line given The points (-1,5) & (3,-3) 1.) Find the Slope You try this one m = (-3 -5)/(3- -1) m = -8/4 = -2

Write an equation of a line given The points (-1,5) & (3,-3) 2.) Plug in one of the points (y - y1) = m(x - x1) (y - 5) = -2(x - -1) y - 5 = -2x -2

Write an equation of a line given y - 5 = -2x - 2 y - 5 +5= -2x - 2 + 5 y = -2x + 3
