Question

How do you find the slope of a line A(1,5) B(3,15)?

Answer 1

The slope of the line running through the two given points is 5.

Explanation:

Use the slope equation: `m=(y_2-y_1)/(x_2-x_1)`, where `m` is the slope, `x_1 and y_1` are one point, and `x_2 and y_2` are a second point.

Let `(1,5)` be `(x_1,y_1)`, where `x_1=1` and `y_1=5`.

Let `(3,15)` be `(x_2,y_2)` where `x_2=3` and `y=15`.

`m=(y_2-y_1)/(x_2-x_1)=(15-5)/(3-1)=(10)/2=5`
