Solve:
2x + 1 = 13
x = 6
100
Find the slope:
(2, 5) and (3, 5)
Slope = 0
100
Give the slope of this equation:
y = -2x + 7
Slope = -2
100
Does this represent a function?
{(2,3), (2, 5), (4, 1)}
No - x-values repeat with different y's
100
What type of association does the scatter plot show? (Positive, negative, or no)
Positive

Name the song...
"Keep it one hundred on the land, the sea, the sky, Pledge allegiance to your hands, your team, your vibes"
Fate of Ophelia by Taylor Swift

Solve:
3(x - 4) = 12
x = 8
200
Find the slope:
(-1, 2) and (3, 10)
Slope: 2
200
Give the y-intercept:
y = 3/4 x - 5
-5
200
Given this table, find the domain.
{1,2,3,4}
200
Is the association strong or weak?
Strong

Solve:
4x + 7 = 3x - 5
x = -12
300
Write in slope intercept form:
Slope: 3
y-intercept: -4
y = 3x - 4
300
A graph has points (0,6) and (3, 0) Find the slope.
Slope = -2
300
Is this a function? Why or why not? 
Yes - passes the vertical line test
300
If you have a regression coefficient of r = -0.234, what does that tell you about your linear model?
It is a weak negative linear correlation.

Name the song...
"And this town's lost its faith, Our colors will fade eventually. So, if our time is runnin' out, day after day, We'll make the mundane our masterpiece"
Oridinary by Alex Warren

Solve
1/2 (8x - 6) = 21
x = 6
400
Write the equation in point-slope form:
Point (2, 7) and slope: -5
y - 7 = -5(x - 2)
400
A graph has the slope of 1/3 and passes through (-6, 0). Write the equation in slope intercept form.
y = 1/3x+2
400
Find the range:
{(3, 7), (2, 1), (10, 7), (-4, -2)}
{7, 1, -2}
400
If you have an r-value of 0.9782, what does that tell you about the linear model?
It is a strong, positive linear correlation.

-31
500
Write the equation for the function:
f(x) = 2x + 5
500
The slope of the trendline shown is -3
What does that slope mean in the real world context?
The value of the car decreases by $3,000 every year.
