100
Is this an expression or equations? Explain your answer.
3(x+4)
Expression because it does not include an equal sign.
100
Translate this sentence into an equation.
15 times a number plus 4 is equal to 17.
15x + 4 = 17
100
Is this equation linear? Explain.
y = x2 - 4
Not linear because it has a variable being squared.
100
What type of correlation do you see in this scatter plot?
Negative Correlation
100
What are the four different signs used in Inequalities?
Less than, greater than, greater than or equal to, less then or equal to.
200
Simplify this expression.
3(x - 4) + 2x
5x-12
200
Solve this equation for c.
c/22 = 4
c=88
200
What are the x and y intercepts in this graph?
x-int ( 14, 0)
y-int (0, 10,000)
200
Identify the slope and intercept of this linear equation.
y = 1/4x - 7
Slope = 1/4
Intercept = (0, -7)
200
What types of inequalties have a closed circle?
greater/less than or equal to
300
Look at the list of points below. Are they a function. Explain.
(2, 4) ( 3, 7) (4 , 6) ( 2, 6) (5, 2).
They are not a function because one of the x-values repeats.
300
Solve the equation for x.
11x - 4 = 29
x = 3
300
What are the four types of slopes that we see with linear equations?
Positive, Negative, No Slope/Slope=0, undefined
300
Write an equation in point-slope form for the line that passes through (3, -2) with a slope of -2.
y+2 = -2(x - 3)
