What is the slope of a line that passes through the point (−2, 3) and is parallel to a line that passes through (3, 7) and (−2, −8)?

Question

Use the slope formula with the two last points $$\frac{ y_{2 } - y_{1}}{ x_{2}-x_{1} }$$

3psilon · Answer

That will give you the Slope for the last two points

Okay let me work it out tell me if its correct..

3psilon · Answer

So the slope would be $$\frac{ -8-7 }{ -2-3} = -15/-5 == $$

3psilon · Answer

Slope = 3

3psilon · Answer

And we know that parallel lines have the same slope

anonymous · Answer

I did it and got 3! thank you!

3psilon · Answer

Did you plug in the slope in y = mx + b form? and plug the first coordinates into that and solve for b?
