Can you help find the slope

Step-by-step explanation:

When given two coordinates, you must use this formula to find the slope of a line:

where m is your slope.

So, plug in your coordinates. Remember, a coordinate is denoted by (x,y). So, for example, your would be -18 and your would be 19.

And that would be your slope. (Answer choice D.)

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
