Use any pair of points to calculate the slope of the line.

Using the pair of points (1, 1) and (0, 0) we have calculated the slope of the line

Solution:

Given that, we can use any two points from cartesian plane,  

Let the two points be (0, 0) and (1, 1)  

We have to find the slope of the line that, passes through the chosen two points.

Now, we know that, slope of a line that passes through is given by:

Substitute these values in "m" formula,

Hence, the slope of the line that passes through (1, 1) and (0, 0) is 1.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
