Write the equation of the line that passes through the points (3,4) and (1,5)
2 answers:
Hi,
Given points (x₁,y₁) = (3,4) (x₂,y₂) = (1,5)FIRST Find the slope of the line. This is general formula to determine the slope m = (y₂ - y₁)/(x₂ - x₁) Plug in the numbers to the formula m = (y₂ - y₁)/(x₂ - x₁) m = (5 - 4)/(1 - 3) m = 1/(-2) m = -1/2SECOND Determine the line equation This is general formula to determine the line equation y - y₁ = m(x - x₁) Plug in the numbers y - 4 = -1/2 (x - 3) y - 4 = (-1/2)x + 3/2 y = (-1/2)x + 3/2 + 4y = (-1/2)x + 11/2 (this is the equation of the line)
