Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.
The y-intercept is (0,7) and the x-intercept is (-2,0).

Step-by-step explanation:
subtract and add
Three tenths is the same as 3/10
the sum of -2 and -28 is -30
3/10 of -30 is the same as the products of the two
3 x -30 / 10 = -90/10 = -9
Your answer is
3(-2 + -28)/10 = -9
You can use linear equations if something is being raised or decreased with the same linear function. Such as temperature or the amount of books that get sold.
