## anonymous 3 years ago line contains points (2, -2) and (-4, 1). Another line graphed in the same coordinate plane contains points (1, 2) and (-3, 4). Based on the slopes of these lines, are they parallel, perpendicular or neither?

Ok so first we have to the slope of both lines

2. anonymous

Do you remember the formula?

3. anonymous

y2-y1/x-x1

4. anonymous

$$(2,-2)=(x_1,y_1)$$ $$(-4,1)=(x_2,y_2)$$

5. anonymous

Parallel

6. anonymous

$$\large {1-(-2) \over -4-(2)}=\frac{3}{6}=\frac{1}{2}$$

7. anonymous

ughhh its -1/2 i forgot the negative

8. anonymous

Parellel?

9. anonymous

Try to find the slope of the second line Use the same process

10. anonymous

I got parellel

Yes the lines are parallel since tehy both have the same slope but like i am assuming you have to solve it not just say its parallel
