Question

What is the slope of the line

Answer 1

We can calculate the slope of a line "m" by means of the following equation:

$m=\frac{y2-y1}{x2-x1}$

Where (x1,y1) and (x2,y2) are two points of a line.

We could take any point where the line passes through, for example, we can take (0,20) and (10,70), then we get:

$m=\frac{70-20}{10-0}=\frac{50}{10}=5$

Then, the slope of the line equals 5
