:)
Answer:
A
Step-by-step explanation:
To calculate the slope m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 7) and (x₂, y₂ ) = (9, 1) ← 2 points on the line
m =
=
= 
A. The distance formula can be written correctly in several different ways
Answer:
c = 
Step-by-step explanation:
Given
4
= 3
c ( change mixed numbers to improper fractions )
=
c ( multiply both sides by 6 to clear the fractions )
25 = 20c ( divide both sides by 20 )
= c , that is
c =
= 1
