Question

What is the slope of the line that contains the points (7, -1) and (-2, -4)?

Group of answer choices

-1/3

4

3

1/3

Answer 1

1/3

Explanation:

Alright, so in this you want to use the slope formula: m=y2-y1/x2-x1. You plug the coordinates of the points into the formula to get the slope. (x1,y1) (x2,y2). So in this problem, 7 is x1, -1 is y1, -2 is x2, -4 is y2. So using the formula, you plug in y2 minus y1, divided by x2 minus x1.

So m (the slope) = -4- (-1) divided by -2-7.

2 negatives make a positive, so -4 + 1 is -3. -2-7 becomes -9. So this is now -3/-9. Again, 2 negatives make a positive, so this is now 3/9. Simplify and the answer is positive 1/3. Hope this helps!
