Question

Which line is parallel to the line that passes through the points (2, -5) and (-4, 1)?

y = -x - 5
y= -2/3 x +3
y = 2/3 x - 2
y = x + 5

Answer 1

Parallel lines have the same gradients.

So if you find the gradient of the given two points, the line parallel to it would have the same gradient.

Answer 2

How do you find the gradient?

Answer 3

You can use this method to find the gradient:

Answer 4

m = 1 - (-5) / -4 - 2

= -1

Answer 5

so y = -x - 5?

Answer 6

Correct :-)

Answer 7

Thank you! I need help with more problems, can i tag you in them?

Answer 8

Yea sure.
