Answer:
B
Step-by-step explanation:
A graph is only a function when there is only one y value for each x value.
A trick is to draw a line through some points on the x-axis, and if the line goes through more than one point. Then it is not a function. (See picture)
Sorry, not all the lines are straight, but you get the point. B is the only one that doesn't have more than one point on the lines I drew.

Graphs of linear functions
Since we are graphing a line, if we have two points we can plot the whole line
We evaluate the line in two points in order to locate two places where it passes through. We say y = h(x)
1. If x = 0 then
h(x) = - 5(0) +3
= 0 + 3
= 3
Then y = 3
2. If x = 2 then
h(x) = - 5(2) +3
= -10 + 3
= -7
Then y = -7
Now, we have two points: (0, 3) and (2, -7)
We locate them and then we plot the only straight line that passes through both points
