Question

What is the slope of the line that passes through the points (-3, 5) and (1, 7)?

Answer 1

the answer is 1/2

Answer 2

Answer: The slope of the line is
`(1)/(2)`

Explanation:

The slope of a line can be calculated with the following formula:

`m=(y_2-y_1)/(x_2-x_1)`

Then, given the points
`(-3, 5)` and
`(1, 7)`, you can identify that:

`y_2=5\\y_1=7\\\\x_2=-3\\x_1=1`

Knowing these values you can substitute them into the formula for calculate the slope:

`m=(5-7)/(-3-1)`

Finally, evaluating, you get that the slope of that line is:

`m=(-2)/(-4)\\\\m=(1)/(2)`
