## lvasquev462 Group Title 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? one year ago one year ago

Ok so first we have to the slope of both lines

2. swissgirl Group Title

Do you remember the formula?

3. lvasquev462 Group Title

y2-y1/x-x1

4. swissgirl Group Title

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

Parallel

6. swissgirl Group Title

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

7. swissgirl Group Title

ughhh its -1/2 i forgot the negative

8. lvasquev462 Group Title

Parellel?

9. swissgirl Group Title

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

10. nickleyswagg Group Title

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
