Find the slope of the line through the points (1, 2) and (5, 10).
m = (10 − 2) ÷ (1 − 5)
m = 8 ÷ (-4) = -2
m = 2
Student switched the correct order of x values
Find the slopes of the following 2 functions:
y = 4x + 7
y = -2x + 4
m=4
m=-2
What is a function?
A relationship between an input and output. A rule that states for each input their can only be one output!

My teacher was hilarious and thats what made it a memorable class.
Find the slope of the line through the points (1, 3) and (4, 9).
m = (4 − 1) ÷ (9 − 3)
m = 3 ÷ 6 = 0.5
m = 2
Student put the x values on top where the y values go
A water bottle contains 200 mL of water. After 5 seconds of filling it, the bottle contains 450 mL. The bottle fills at a constant rate.
Find the rate of change and be ready to share what it means in context of this question.
rate of change = 50
the water bottle fills at 50 ml per second

Find the slope of the line through the points (−2, 3) and (4, −5).
m = (-5 − 3) ÷ (4 − 2)
m = -8 ÷ 2 = -4
m = -4/3 = -1.33
Student made a mistake in subtracting the negative 2. Subtracting a negative turns into addition.
Alex has already saved $40 toward a concert ticket. Each week, Alex saves an additional $15.
1. Create an equation in the form y = b + mx
2. What does x and y represent?
y = 15x + 40
x is the number of weeks
y is the total $ saved
We can find the __ intercept when y = 0
We can find the __ intercept when x = 0
Find the x intercept of the equation y = 4x - 8

Find the slope of the line through the points (0, 1) and (3, 7).
m = (7 − 1) ÷ (3 − 0)
m = (6,3)
m=2
Student followed the formula until instead of dividing, wrote slope as a point
Two phone companies offer different monthly plans.
Plan A: Costs $20 to start and $15 per month.
Plan B: Costs $50 to start and $10 per month.
Create two equations and explain which phone plan is a better deal for your family!
y = 15x +20
y = 10x + 50
Plan B will save my family $$$
