Answer:
A) Vertical.
Step-by-step explanation:
It must pass the vertical line test. That is it must not have any vertical line passing through more than one point on the curve. If it does then it is not a function.
Thus , for example, a circle graph would not be a function.
Given:
1 inch : 18 kilometers
Let us use the ratio and proportion method:
a:b = c:d where ad = bc
0.8 inches is <u>14.4 kilometers</u>
1 : 18 = 0.8 : x
x = 0.8 * 18
x = 14.4 km
1.4 inches is <u>25.2 kilometers</u>
1: 18 = 1.4 : x
x = 18 * 1.4
x = 25.2 km
2.1 inches is <u>37.8 kilometers</u>
1 : 18 = 2.1 : x
x = 18 * 2.1
x = 37.8 km
First you subtract 6 from both sides to get:
4h=24
Then divide by 4:
h=6
