Answer:
This table represents a function
y is 1.3 times x
y=1.3x
Step-by-step explanation:
In a ratio of 7:3, for every 7 adults you have 3 children. So 30% of the total are children. I.e. if you have 10 people .7 times (10) are adults or 7 and .3 times (10) are children or 3. So for 370 people, .3 times 370 are children, or 111.
You need to find the slope of the line too. they use m to represent slope.

point slope equation is y - y1 = m(x -x1)
they said to use point (-2, -2)
y -(-2) = 1(x -(-2))
y +2 = 1(x +2)
You do 420/4 so therefore it would be 105 miles per square feet of the square.
