Answer:
Slope = -4
Step-by-step explanation:
Given points are :
(-1,30) and (4, 10)
We need to find the slope of the line that passes through these points.
We know that, the formula for the slope of line is given by :

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10
Put values in the above formula.

So, the slope of the line is -4.
Sorry I don't what the answer would be for A. But B would be (3,13)
The answer is 8700. there you go sir or ma'm!
Answer:
8
Step-by-step explanation:
Fill in the variable value and do the arithmetic.

___
Of course, the fraction can be simplified first:

C.
Notice that both sides point towards infinity. This means that it is an even degree. Also, it crosses the x axis twice, which makes it have 2 real zeroes.
