Question

Please explain, everytime I try I get it wrong. Thank you

Answer 1

`slope = - (8)/(5)`

Explanation:

So it looks like on the line, we have two dots.

Let's find those points, starting from the left one.

The left point is: (-1, 4) --- (x1, y1)

The right point is: (4, -4) --- (x2, y2)

**These are in (X, Y) form**

Now to find the slope, you use this equation

`m = (y2 - y1)/(x2 - x1)`

Now let's plug our numbers into this equation

`m = ( - 4 - 4)/(4 - ( - 1)) = ( - 8)/(5) = - (8)/(5)`

Two negatives make a positive, so 4-(-1) is the same as 4+1.
