b = y - mx.
If y = mx + b, then x = (y-b)/m (for m not equal to zero).
A straight line equation
y = mx + b y - mx = b
in the equation: y=mx+b , the y-intercept is represented by "b".
It is the equation formula for a straight line equation.
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
That is the standard equation to graph a line.
In the equation y = mx+b, b is the y-axis intercept.
