Question

What is the slope passing through the points (-2,4) and (7,-3)?

Answer 1

The slop passing through `(-2,4) and (7-3)` is `-7/8`

Explanation:

The slope formula is `(y_2-y_2)/(x_2-x_1)`

So the values for those variable are:
X1 = -1
X2 = 7
Y1 = 4
Y2 = -3

So let plug those number back into the formula:

`(-3-4)/(7-(-1)` = `-7/8`

Ok so let examine `7-(-1)` as you may of been confused on how I got `8`. So the negative outside of the parentheses is -1 and it is implied that it is always -1 if no number is written outside of the parentheses. So -1 times -1 gives us positive 1 which changes the sign from subtraction to addition thus being `7+1=8`.
