Solve For X
Solve for x:
4 + x = 12
x = 8
Solve for a:
a + b = c
a = b - c
What is y = mx + b called?
Slope-intercept form.
The scatterplot goes up a little bit. What kind of correlation is this?
Weak positive.
Amy
Solve for x:
4x = 12
x = 3
Solve for a:
ab = c
a = c/b
In y = mx + b, what does b represent?
y - intercept
The scatterplot goes down sharply. What kind of correlation is this?
Strong negative.
What foreign language does Mr. Smith speak fluently?
German
Solve for x:
3x + 12 = 72
x = 20
Solve for a:
ad + b = c
a = (c - b)/d

Slope
A graph has a perfect positive correlation. What is a possible value for r?
Anything above 0.75, preferably 1.
Name one country in Eastern Europe.
Poland, Czech Republic, Slovakia, Slovenia, Romania, Belarus, Ukraine, Latvia, Estonia, Lithuania, Hungary, Moldova, Serbia, Bulgaria, Bosnia
4(x + 2) = 24
x = 4
Solve for a. Simplify:
ad + bd = c
a = c/d - b
What is the formula for slope?
(y2-y1)/(x2-x1) OR rise/run OR changey/changex
A graph has a loose negative correlation. What is a possible value for r?
Anything from -0.1 to -0.5.
What is the capital city of Germany?
Berlin
Solve for x:
2(x+5) - 4(x+6) + 12(x-1) = 19
x = 4.5
Solve for a:
e(ab + dc) = f
a = f/eb + dc/b
If y = 2x + 4, and x = 5, what does y=?
y=14
