Standard Form

What does it take to be a line in standard form?

Ax + By = C

Clear the fractions and A has to be positive!

2x + 5y = -7

Slope-Intercept Form

This form is graph-friendly. All you have to do is graph the y-intercept (set x equal to zero) and then count the slope on the graph.

y = mx + b

m is the slope and b is the intercept

Point - Slope Formula

If you know one point and the slope of a line, you can use the point-slope formula to write an equation for that line.
