Help if you know how to do thus​

A)

Step-by-step explanation:

For this question, we can use the rise over run method, which means y over x.

So count how many it takes for the point on top to get to the bottom by x and y.

It takes 7 spaces down (y)  and 4 spaces to the right (x)

So do rise over run and we get

Meaning that B and C are incorrect. Now what about A and D?

Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.

A. is correct.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
