Answer:

The slope of this line would be 10.

Step-by-step explanation:

In order to find the slope of the line, you would use the slope formula below.

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

m = (7 - -13)/(9 - 7)

m = 20/2

m = 10

If 40% are boys, 60% are grills.

As fractions:

4/10 = 2/5 are boys

6/10 = 3/5 are grills

70% or 7/10 of the boys arrive by car:

(2/5)(7/10) = 14/50 = 7/25

And 60% or 3/5 of the grills arrive by car:

(3/5)(3/5) = 9/25

So in total we have 7/25 + 9/25 = 16/25 = 64/100 = 64%

64% chance that a child arrives by car.
