Question

Can you help me with this it’s been due

Answer 1

- (4, 5) and (4, -2) -

We can find the slope by using rise/run

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{5-(-2)}{4-4}$

As expected, the slope is indeed undefined. The denominator can't be 0 but this one has denominator that's 0 which is undefined.

Meaning that, when the x-value for both ordered pairs are the same, the slope will be undefined.

For the graph, It should be like this below in the picture.
