Answer:
Step-by-step explanation:
western beach: y = -2x + 100
dunes beach : y = 5x + 20
set the equations equal to each other
-2x + 100 = 5x + 20
100 - 20 = 7x
80 = 7x
80/7 = x
x ~ 11.43 years
Answer:
Slope = 4
Step-by-step explanation:
This is an equation of a line in the format y = mx + b
Lets match the two equations vertically to see which term is which
y = mx + b
y = 4x - 3
m is the slope, and it matches with the term "4"
That means that 4 is the slope
Parts of y = mx + b
- y : output
- m : slope
- x : input
- b : y - intercept
