What is the slope?
100
Is this a function? Why or why not? f(x)=2x
What is yes this is a function. This is a function because after you multiply your x value by 2 multiple times, there is a pattern. If there is a pattern, you know that it is a function.
100
Are all functions relations?
What is yes.
100
What is the independent variable in the following statement: 8oz. cup and amount of water in it
What is amount of water in it.
100
What 2 intercepts do you use in slope?
What is x and y intercepts.
100
Using the coordinates given and the formula for slope, what is the slope of this straight line? (1,5) and (-2,10)
What is 5/-1.
200
Is this a function? (5,9) , (2,7) , (6,0) , (3,8) , (1,6)
What is yes. This is a function.
200
What is one way to "test" your equation to know if it really is a function.
What is vertical line test.
200
use the statement "is a function of" with the following sentence. amount of money spent and number of flowers bought
What is amount of money spent depends on the number of flowers bought.
200
What 4 types of slope are there?
What is positive, negative, zero, undefined.
200
Using the coordinates given and the formula for slope, what is the slope of this straight line? (42,-6) and (-10,9)
What is 3/-52.
300
Is this a function? Back your answer up with a t-chart and/or a graph if needed. f(x)= -2x+5
What is yes this is a function.
300
In mathematical terms, what is another word for x?
What is domain or input.
300
What is the slope in y=3x+6?
What is rise 3 run 1
300
What is slope?
What is slope is describing how steep a straight line is.
300
Using the coordinates given and the formula for slope, what is the slope of this straight line? (16,3) and (-2,-5)
What is 1/-9.
400
Is this a function? Why or why not? (3,7) , (6,9) , (3,6) , (4,0) , (2,3)
What is no because each input does NOT correspond to exactly one output.
400
What is the definition of a function?
What is a relation in which one input corresponds to exactly one output.
400
What does b stand for in y=mx+b?
What is the y intercept.
400
When using slope what variable is used?
What is (m).
