Step 1: Define

Point (2, 9)

Point (8, 1)

Step 2: Identify

(2, 9) → x₁ = 2, y₁ = 9

(8, 1) → x₂ = 8, y₂ = 1

Step 3: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{2+8}{2},\frac{9+1}{2})$
[Fractions] Add: $\displaystyle (\frac{10}{2},\frac{10}{2})$

The water level of a river is 170 feet. The river recedes 4 feet each year. Ingrid claims that the equation that represents this

Irina-Kira [14]

1. y=f(x)=170x-4 is a function with variable x representing a year.

2. Let's consider the difference between 2 consecutive years, say year 3 and year 4

f(3)=170*3-4
f(4)=170*4-4

we expect f(3)-f(4) to be 4 since after 4 years, the water will be 4 feet less than after 3 years.

check: f(3)-f(4)=(170*3-4)-(170*4-4)=170*3-4-170*4+4=170*3-170*4=170*(3-4)=170*(-1)=-170
