Question

A line is drawn so that it passes through the points (-3,0) and (1.4). What is the slope of the line?

Answer 1

Answer:
`m=1`

Explanation:

For this exercise you can use the following formula for calculate the slope:

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

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

`y_2=0\\y_1=4\\\\x_2=-3\\x_1=1`

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

`m=(0-4)/(-3-1)`

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

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