Question

Angelique Calculated the slope of a line that passed through points (-5,4) and (2,-3) her work is shown below. identify her error and correct her mistakes.

Answer 1

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 5, 4 ) and (x₂, y₂ ) = (2, - 3 )

m = $\frac{-3-4}{2-(-5)}$

Her error was subtracting 5 from 2 instead of - 5 from 2

m = $\frac{-7}{2+5}$ = $\frac{-7}{7}$ = - 1 ← corrected solution
