The equation is y = 40x + 125

The slope of this situation is $40 per month while the y-intercept is $125 for adoption.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Let y represent the total cost of keeping a dog for x months. Hence:

y = 40x + 125

The slope of this situation is $40 per month while the y-intercept is $125 for adoption.

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$
