M=-5 (7,9) standard form

Question

M=-5 (7,9) in standard form

Answer 1

Standard Form of a Linear Equation: Ax + By = C. A, B, and C must be integers {...-3, -2, -1, 0, 1, 2, 3...}

M is the Slope of the line and the line passes through the point (7,9) where 7 is the x₁ value and 9 is the y₁ value.

I like to use the Point-Slope Form to solve this:

y - y₁ = m(x - x₁)

y - 9 = -5(x-7) Distribute the -5

y - 9 = -5x + 35 Add 9 to both sides of the equation

+9 +9

y = -5x + 44 Move the -5x to the other side of the equation to put it in standard form

+5x +5x

5x + y = 44
