<h3>Answer:</h3>
x = -2
<h3>Explanation:</h3>
The line represents the output value (y) for a given input value (x). Where the lines cross, the output values are equal. These lines cross at x=-2.
We have been given that during one period extreme cold, the average daily temperature decreased 
degree F each day. We are asked to find number of days it will take for the temperature to decrease by 9 degree F.
First of all we will convert our mixed fraction into improper fraction.
Now we will divide total temperature change (9) by average daily temperature change (
) to find number of days.
Dividing a number by a fraction is same as multiplying the number by reciprocal of the fraction.
Therefore, it will take 6 days for the temperature to decrease by 9 degree F.
Slope is y2-y1 divided by x2-x1. It doesn't matter which you put it for x2 or y2, but make sure to keep it consistent for whichever you choose to do first.
20 - 8/-18-1
12/-19
Since you can't simplify, the slope is 12/-19
