## lvasquev462 2 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?

1. swissgirl

Ok so first we have to the slope of both lines

2. swissgirl

Do you remember the formula?

3. lvasquev462

y2-y1/x-x1

4. swissgirl

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

Parallel

6. swissgirl

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

7. swissgirl

ughhh its -1/2 i forgot the negative

8. lvasquev462

Parellel?

9. swissgirl

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

10. nickleyswagg

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
