Converting Standard Form to Slope Intercept Form

What is the standard form of a linear equation?

• y = mx + b

• ax + by = c

• x = my + b

• ax - by = c

Why do we convert linear equations from standard form to slope-intercept form?

• To make them easier to graph

• To solve for x

• To find the y-intercept

• To eliminate fractions
