What is the slope of the line?  $y=5x+10$  

•  $m=5$  

•  $m=-5$  

•  $m=\frac{1}{5}$  

•  $m=-\frac{1}{5}$  

Find the equation of the line with the slope -2 and goes through the point

(-10, -3).

• $y=-2x-23$

• $y=-2x+17$

What is the slope of the equation
 $-30x+10y+100=0$  

•  $m=3$  

•  $m=-3$  

•  $m=\frac{1}{3}$  

•  $m=-\frac{1}{3}$  

 $x=5y+15$  

Solve for y in terms of x.

•  $\frac{x}{5}-3=y$  

•  $\frac{\left(x-5\right)}{15}=y$  

•  $\frac{x}{15}-\frac{1}{5}=y$  

•  $\frac{x}{5}-15=y$  

 $w=\frac{3}{5}t-4$  

Solve for t in terms of w.

•  $\frac{5}{3}w+\frac{20}{3}=t$  

•  $\frac{5}{3}w+4=t$  

•  $\frac{3}{5}w+\frac{12}{5}=t$  

•  $\frac{3}{5}w+4=t$  

Using the points find the slope and then use one of the points to find the y-intercept to create an equation.

• $y=-.5x+5.5$

• $y=2x-2$

• $y=.5x+2.5$

• $y=2x+2$
