Step-by-step explanation:
Sprints = $39.99 +&0.45
Verizon= $44.99+$0.40
Step 1: Equate the values
Step 2 :Collect like terms and simplify
Step 3 :Divide both sides of the equation by 0.05
Step 4 :Simplify
B
Establish the equation of the line in slope-intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (- 3, - 3 ) and (x₂, y₂) = (3, - 1) ← 2 points on the line
m = =
=
the y-intercept is (0 , - 2 ) ⇒ c = - 2
y = x - 2 ← equation of line
This is a strict inequality since the line is broken, hence
y > x - 2 → B
