Question

2. what is the slope of the line that passes through the pair of points (-2,7) (18,1)

Answer 1

Answer:

Step-by-step explanation:

slope = y₂-y₁/x₂-x₁

$=\frac{1-7}{18-(-2)}\\\\ =\frac{-6}{18+2}\\\\ =\frac{-6}{20}\\\\ =\frac{-3}{10}$

1-7 = -6. Here if two numbers have different sign, then subtract and put the bigger numbers sign for the result.
