So the relationship here seems to be going by two. Every time the x-value decreases from -2 to +7, the y-value is decreasing by 2. Since you're looking for when x=0, the only number that could possibly do that is when y=10. Before x=1, the y-value can increase by two so it would go from 8 to 10 since we know the relationship for the y-values is 2. Therefore your answer should be D.) 10

Hope this helps!

Answer:

D. 10

Step-by-step explanation:

gradient from (-2,14) to(7,-4)

gradient becomes

-4-14/(7-(-2))

-18/9

gradient =-2

y=-2x+c

when x=-2,y=14

14=-2(-2)+c

c=14-4

c=10

x y

-2 14

1 8

2 6

4 2

7 -4

We plot the data on a graph. The gradient was calculated as change in y over change in X

look at the excel document for the graph

Equation of a line graph was used y=mx+c

y=vertical axis

x=horizontal axis

C=y intercept
