I really need understanding someone please help.
The Standard Form for a linear equation is Ax + By = C
(A ≥ 0)
Because we have coordinates of a point on the line and slope, let's use Point-Slope Form of linear equation
y - y_{1} = m(x -x_{1})
y - (- 4) = (1/2)(x - 6)
y + 4 = (1/2)x - 3
y - (1/2)x = - 3 - 4
Let's multiply both sides of equation by (- 2)
x - 2y = 14
~~~~~~~~~
6 - 2*(- 4) = 14
6 + 8 = 14
14 = 14
