Mrs. hicks has 35 students in her chemistry class. the ratio of girls to boys is 3: 4. how many girls does she have in her class? let both antecedents represent girls and let both consequence represent total students.

Explanation:

Pick any two rows from the table to plug into the slope formula.

I'll pick the rows where every value is positive (rows 3 and 4)

Using the slope formula, we get the following:

m = (y2-y1)/(x2-x1)

m = (1-5)/(2-1)

m = -4/1

m = -4 is the slope and it's the rate of change

For any linear function, the slope and rate of change are the same thing.
