Question

Which expression can be used to fine the slope of a line containing the points (-3,2) and (7,-1)

Answer 1

Hello there! you can use the expression
`( y_(1)-y_(2))/(x_(1)-x_(2) )`!

To find slope, subtract the y values over the x values.

In this case:

2 - - 1 / - 3 - 7

3 / -10

So, -3/10 would be the slope of these points.

Hope this helps, have a great day!
