Slope

Slope

VA SOL 7.10

Slope or rate of change, denoted by m, is equal to:

•  $\frac{vertical\ change}{horizontal\ change}$  

•  $\frac{change\ in\ y}{change\ in\ x}$  

•  $\frac{rise}{run}$  

•  $\frac{\Delta y}{\Delta x}$  

 $m=\frac{rise}{run}=\frac{2}{4}=\frac{1}{2}$  

We can find the slope when given a graph by selecting one point and counting how many spaces up or down (rise/vertical) and then how may spaces left or right (run/horizontal) until we reach the second point.

In the formula y=mx+b, m is the slope. This is known as slope-intercept form.

• When slope or m=1, the formula will look like y=x+b.

• When b=0, the formula will look like y=mx.
