Question

this is about slope

Answer 1

Ok the slope question
We should definitely know the slope formula:

m=y₂-y₁/x₂-x₁

m=$\frac{-2-2}{-1-(-4)}$
   =$\frac{-4}{3}$

The slope of the line that passes through points (-4, 2) and (-1, -2) is $\frac{-4}{3}$

Answer 2

Please see the pic, I'd also solved it.
