y=5x/8+3
To write a linear equation in standard form, move each variable to the left of the equation and simplify.
Ax + By = C
Move 5x/8 to the side of the equation because it contains a variable.
y-5x/8=3
A must be positive, so multiply both sides of the equation by -1.
-1 * (y - 5x/8) = -1*3
Simplify the left side of the equation:
5x/8 -y = -1*3
Multiply -1 by 3 to get -3
5x/8-y=-3
