# 7000 shirts can be sold for $61.00 and 8000 shirts can be sold for $52.00, How do you give linear equation p=mn+b?

##### 1 Answer

#### Explanation:

We are basically given two points: (7000, 61) and (8000, 52). Therefore we can use the point-slope formula to find the linear equation in slope-intercept form.

First, we need to find the slope. The formula for the slope given two points is:

Where

Substituting the points we were provided gives:

Next we can use the point-slope formula to give us the linear equation:

The point-slope formula states:

Where

Using the slope we calculate and either of the points we can substitute to get the equation:

Now we can solve for
