Complete the equation of the line through (-10,-7) and (-5, -9).
use exact numbers,

Step-by-step explanation:

A line in 2-dimensional space has the following general equation:

Where m is the slope of the line, and b just a number

the slope can be obtaine using th following formula:

The point 2 is the one with the smallest value for x, that is (-10,-7) and the Point 1 is any other that belongs to the line, in this case, (-5,-9)

Resulting that

To find the other term we can use any other point, I prefer us the first one so...

We have the following equation:

Resulting that b=18

I just have to eval the point (-10,-7) in the equation stated at the beginning  knowin that m was calculated previously.
