Answer:
90
Step-by-step explanation:
30x3=90
A relation is (also) a function if every input x is mapped to a unique output y.
In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:
- The first graph is exactly a vertical line, so it's not a function.
- The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
- The third graph is not a function, because you can draw vertical lines that cross the graph twice.
- Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
- The fifth graph is a function, because every vertical line crosses the graph once
- The last graph is a function, although discontinuous, for the same reason.

Answer: 24.5 or 25 1/2
The equation of proportional relationship is of the form:
where m is the slope.
Drawing it is fairly easy, you start from the origin (0, 0) and you draw a diagonal staight line. The inclination of the line depends on the value of m. See picture attached.
