Question

What is the slope? I really suck at math

Answer 1

This is not a function, therefore, the slope is undefined.

I would propose using a VERTICAL LINE TEST. This test is to check vertically if there are more than one coordinates/points in one vertical line. That line is vertical, and there are many points, which makes it not a function. And if it is not a function, then the slope is undefined.

The slope, also, is the average rate of change. The formula you use to find the slope is $\frac{y(2) - y(1)}{x(2) - x(1)}$. You would take any coordinates and insert them into this formula.

Answer 2

Slope would be undefined because there are many many y-values for one x value. This is impossible for ANY function. To be specific, the correct equation that names the graph is x=4. Please note that this is not a function. If it goes straight up, it is UNDEFINED!!! 

Hope I helped!


The answer is D
