Question

Helloo! I forgot how to do these types of problems :/

Answer 1

To find the slope of the line passing through the points:

`(3,8),(7,-7)`

We need to use the slope of the point-to-point formula for the line equation:

`y-y1=(y2-y1)/(x2-x1)\cdot(x-x1)`

The slope is, therefore:

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

The points are:

x1 =3, y1 = 8 and x2 = 7, y2=-7. Then:

`m=(y2-y1)/(x2-x1)=(-7-8)/(7-3)=(-15)/(4)\rightarrow m=-(15)/(4)`

Then, the slope of the line passing through points above is m = -15/4.
