1. Which graph represents a relation that is not a function?
1 answer:
The second one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).
In every function, you must have a single "y" value for each "x" in the domain.
__________
In order to see it better, you can trace a vertical line onto that graph.
If that line and the graph intersects in more than one point, then that graph doesn't represent a funcion.
Look into the attached picture and see. That vertical red line and the graph intersects in two distinct points. Therefore, it can't represent a function.
Any doubt? Please, comment below.
I hope it helps. :-)

The answer is
Step-by-step explanation:
If two equations are parallel it means that both their gradients are equal. We were given the equation:
in order to find the gradient of this equation that we are given we have to ensure that it is in its simplest form:
Therefore the gradient of the parallel line with points (-2, 4) is also -5/2
Step-by-step explanation:
draw the last one by yourself.
im sure you can do it buddy.
