1 Writing equations given 2 points on the line

2 Write the equation of the line that goes through the points (1, 6) and (3, -4) m = y₂ - y₁ x₂ - x₁ -4 - 6 3 - 1 -10 2 Y = mX + b -5 6 = (-5)(1) + b 6 = -5 + b +5 11 = b Y = -5X + 11

3 Write the equation of the line that goes through the points (-1, 1) and (0, 3) m = y₂ - y₁ x₂ - x₁ 3 - 1 0 – (-1) 2 1 Y = mX + b 2 3 = (2)(0) + b 3 = 0 + b -0 3 = b Y = 2X + 3

4 Write the equation of the line that goes through the points (-4, 3) and (8, 3) m = y₂ - y₁ x₂ - x₁ 3 - 3 8 – (-4) 0 12 Y = mX + b 0 3 = (0)(8) + b 3 = 0 + b -0 3 = b Y = 0X + 3 Y = 3

5 Write the equation of the line that goes through an x intercept of 3 and a y intercept of -2 m = y₂ - y₁ x₂ - x₁ -2 - 0 0 – 3 -2 -3 Y = mX + b 0 = (⅔)(3) + b 0 = 2 + b -2 -2 = b Y = ⅔X - 2 (3, 0)(0, -2) 2 3
