Question

Find the slope in the line through the points p1 = (7, -6). p2 = ( - 9, 3).

Answer 1

Recall that the slope of the line that passes through the points (x₁,y₁), and (x₂,y₂) is given by the following formula:

`m=(y_2-y_1)/(x_2-x_1)\text{.}`

Therefore, the slope of the line that passes through p1 and p2 is:

`m=(-6-3)/(7-(-9))\text{.}`

Simplifying the above result we get:

`m=(-9)/(16)\text{.}`

Answer:

`-(9)/(16)\text{.}`
