What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope and b is the y-intercept.

How do you convert the standard form of a linear equation to slope-intercept form?

Back

To convert from standard form (Ax + By = C) to slope-intercept form (y = mx + b), solve for y to isolate it on one side of the equation.

How do you find the y-intercept from a linear equation in standard form?

Back

To find the y-intercept from a standard form equation (Ax + By = C), set x = 0 and solve for y.
