Front

Convert the standard form equation x + 4y = 8 to slope-intercept form.

Back

To convert, solve for y: 4y = -x + 8, so y = -\frac{1}{4}x + 2.

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).
