What is the formula for slope?

• $Y=mx+b$

• Y = $M\ =\frac{Y_2-Y_1}{X_2-X_1}$

• $Y-Y_1=m\left(X-X_1\right)$

Slope is a ration written as...

• $m=\frac{Rise}{Run}$

• $m=\frac{run}{rise}$

• $m=\frac{Y-int}{X-int}$

• $m=\frac{x-int}{y-int}$

Slope-intercept form is written as...

• $Y-Y_1=m\left(X-X_1\right)$

• $Ax\ +\ By\ =\ C$

• $Y\ =\ mx+b$

X-Intercept

• (0,0)

• (0,a)

• (0,b)

• (a,0)
