Please add an explanation to your answer.

H. t = -3h + 45

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Coordinate Planes

Slope-Intercept Form: y = mx + b

Slope Formula:

Step-by-step explanation:

Step 1: Define

Identify variables.

y-intercept (0, 45)

Point (5, 30)

Step 2: Find Slope m

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

Step 3: Find Equation

Our variables are h (x-axis) and temperature in °F (y-axis). Our slope tells us that for every increase in hours h, the temperature decreases by -3 °F. Our y-intercept tells us what temperature °F it was in the beginning (45 °F).

And we have our final answer!

Step-by-step explanation:

t =-3h + 45

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
