The slope of the line is 
Explanation:
Given that a coordinate plane with a straight line passing through the points
,
and 
We need to determine the slope of the line.
The slope of the line can be determined using the formula,

Since, the points
,
and
lie on the straight line and the slope of all the points in a straight line have the same slope.
Hence, let us consider the points
and 
Let us substitute these points in the slope formula, we have,

Simplifying, we get,

Dividing, we get,

Hence, the slope of the line is 
She can not fit more than twenty rows in the class so anything equal to twenty or less (not including zero or negative numbers) would be fine. We don't have a limit for how many chairs in a row so I'm answering assuming that is not a problem so 20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2, or 1 row(s) would be possible

So, to turn this into a percentage, we have to turn this into a decimal by dividing:
80/100 = 0.80
80% of tart cherries are produced in this state.
