Answer:
8
Step-by-step explanation:
Using the Heron's formula we can find that the total area of the triangle is 84 inches.
Then, to find the height of the triangle, you have to multiply the area by 2 since the formula for the area of a triangle is (h*b)/2
Now, when we multiply 84 and 2 we get 168, so you have to divide 168 by 21 to find 8.

Step-by-step explanation:
Simply look at the given x values in the table and whatever x equals in the table, put that value in the equation. For example, y = -x + 7. In the table x value, 0 is given, so the equation will now be y = 0 + 7. So y = 7 and so forth.
To graph, you take the given x value, 0, and the y value you solved for, 7. Your point on the graph would be (0 , 7). Continue repeating these steps till you complete the table and your graph. :)
