100
Explain what makes a set of ordered pairs a function.
Each x input goes to one y output.
100
What is the slope of the line with the equation, y = 3x + 2?
What is 3
100
The point on a line that intersects the y-axis.
What is y intercept
100
What is the slope and y-intercept of the line y = -3x - 6?
What is -3 and (0, -6)
100
Is the point (3, -4) a solution to the equation 2y + 3x = -6?
no
200
Is this a function? Explain. (4, 2) (5, 4) (5, -3) (6, 3) (7, 0)
No, because the input 5 is assigned to two different y values
200
Plot the points (3, -4) and (4, -5). Find the slope.
What is -1
200
What is the y-intercept of the line whose equation is y = 4x + 2?
What is 2 or (0, 2)
200
Does the graph y = (1/2)x + 4 contain the point (2,5)? EXPLAIN your answer.
Yes, the graph contains the point(2,5) because (2, 5) is a solution to the equation - it satisfies the equation.
200
What is the value of x if the point (x, 3) lies on the line whose equation is 2x + 4y = 30?
What is 9
300
What is the name of the test that you can use to determine if a graph is a function?
Vertical Line Test
300
Given the points (9, 4) and (6, 4), what is the slope AND give the equation of the line.
What is 0 and y = 4
300
What is the y-intercept of the line whose equation is y = x?
What is 0
300
What do you know about y = -2x -1 and 2x + y = 8
They are parallel since they both have a slope of -2 and different intercepts
300
Write the equation of the line whose slope is (3/4) and whose X-intercept is -2.
What is y - 0 = 3/4(x - 2) or y = (3/4)x - 3/2
400
If the domain of the function f(x) = x is {-5, 3, 7}, what is the range?
{-5, 3, 7}
400
What is the slope of a vertical line through the point (2,6) AND give the equation for the line.
What is "undefined" and x = 2
400
What is the x-intercept of the line whose equation is y = 4x + 6?
What is -3/2
400
Describe the line whose equation is x = -4.
is is a vertical line with an x-intercept of -4
400
Write the equation of the line whose slope is 1/2 and whose y-intercept is 9 in STANDARD FORM
What is -1x + 2y = 18 or x - 2y = -18
500
If you were given a graph of a circle, would it be a function? Explain.
No, it fails the vertical line test
500
What is the slope of the line parallel to 3x + 5y = 10
What is 5/3
500
What is the y-intercept of the equation x = -3?
There is not y interept
500
Are 3x - 5y = 7 and y - 5 = 3/5(x - 4) perpendicular lines?
No, one slope is 5/3 and the other is 3/5. To be perpendicular, the second slope would have to be -3/5.
500
