Answer:
slope = 40
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (2, 80) and (x₂, y₂ ) = (4, 160) ← 2 points on the line
m = =
=
= 40
Answer : B
the distance between the points (4,3) and (2,-1)
We apply distance formula
(x1,y1) is (4,3)
(x2,y2) is (2,1)
d^2 = 4+16 = 20
Take square root on both sides
So
the distance between the points (4,3) and (2,-1) is 2sqrt(5)
