Parallel Lines

Select ALL the lines that are parallel to each other.

• $y=2x-6$

• $y=-2x+12$

• $y=\frac{1}{2}x-9$

• $y=2x-13$

• $y=2x$

Two lines that are parallel will have.....

• The same slope

• The opposite signed slope

• The reciprocated slope

• Any slope

If a line has a slope of 6. What should the slope be if another line is parallel to it?

• $m=-6$

• $m=6$

• $m=\frac{1}{6}$

• $m=-\frac{1}{6}$

Looking for a line that is parallel to:

 $y=\frac{2}{3}x+5$  
Check ALL that it could be.

•  $y=\frac{3}{2}x-8$  

•  $y=-\frac{2}{3}x-4$  

•  $y=\frac{2}{3}x+12$  

•  $y=\frac{3}{2}x$  

•  $y=\frac{2}{3}x$  

If a  line is parallel to:

 $y=\frac{4}{5}x+3$  
What is the slope of that line?

•  $m=\frac{5}{4}$  

•  $m=-\frac{4}{5}$  

•  $m=-\frac{5}{4}$  

•  $m=\frac{4}{5}$  

What is the slope of a parallel line to:

 $y=4x+9$
