Answer:

-1

Step-by-step explanation:

Use the rule y2-y1 / x2-x1

y1 = h

y2 = 9

x1 = -9

x2 = -8

so you get

9-h / (-8) - (-9) = 10

cross multiply to get

9-h = 10

so -h = 10-9

so h = -1

Answer:

First, find 2. Then find the 3/10 mark following 2 (if there is one). That is where you put your point. If there are no 10ths markings, it is up to you or your teacher how to plot it.
