Quick facts for Linear Equations

• If 0 is in the numerator, then the slope is 0. • If 0 is in the

denominator, then the slope is Undefined.

Quick facts for Linear Equations

•Horizontal lines are y = # , so you need use the y value in (x, y)•Vertical lines are x = # , so

you need use the x value in (x, y)

Quick facts for Linear Equations

• To find the y-intercept, let x = 0. Solve for y.• To find the x-intercept, let y = 0. Solve for x.

Quick facts for Linear Equations

• An x = # is parallel to an x = # • A y = # is parallel to a y = #

• An x = # and y = # are perpendicular

Quick facts for Linear Equations

Point-Slope form y – y1 = m(x –x1)

simplifies to Slope-Intercept Form

(y = mx + b)
