slope
y-intercept
parallel
equation ?
function ?
100
in y = Mx + b, this is the slope.
What is M
100
the line crosses this axis at the y-intercept.
What is the y-axis.
100
these lines never intersect
What is parallel lines
100
in the equation y=Mx+b, M always equals 0 for this type of line.
What is a horizontal line
100
this test can be used to determine whether a graph represents a function or not
What is the vertical line test
200
go up 4 and over 3
What is a slope of 4/3
200
x always equals this value at the y-intercept point.
What is x=0.
200
if two lines are parallel, this is the variable in both equations y=Mx+b that must be the same.
What is M or slope.
200
Which of these lines is vertical? y = -4 x = -4
x = -4
200
this is how you can tell a set of points is not a function
What is a double input, multiple x-values, an x has more than one y, or an input has more than one output.
300
when the line goes down or descends
What is negative slope
300
in the equation y=-2x+6, this is the y-intercept.
What is 6, or (0,6)
300
this is how you know y=2/3(x)+4 and y=2/3(x)-6 are parallel.
What is slope of 2/3
300
y = -2x + 3 y = 5x + 3 What can you say about the relationship between these two lines?
They have the same y-intercept or they intersect at (0, 3).
300
(0, 2) Why is this set of points not a function? (1, 3) (2, 4) (3, 5) (-2, 2) (1, 7)
Because there is a double input, x has more than one y, an input has more than one output
400
this means go down 7 and over 2
What is slope of -7/2
400
the two lines y=-2/3(x) -7 and y=1/2(x) + (-7) cross at this point.
What is -7 or (0,-7)
400
y = (-3/7)x - 2 y = (-3/7)x + 4 At what point do these lines intersect?
They don't because since they have the same slope, they are parallel.
400
what is the definition of a function?
each x has only one y each input has only one output
500
What is the same about all these lines? y = (-3/-6)x + 0 y = (5/10)x - 3 y = (-2/-4)x - 2 y = (4/8)x + 6
They all have the same slope of 1/2.
500
(-4, 11) which of these is the initial value? (-3, 9) (-2, 7) (-1. 5) (0, 3) (1, 1)
(0, 3)
500
At what point do these lines intersect? Line 1 Line 2 (0, 0) y = -2x + 4 (1, 2) (2, 4) (3, 6)
They intersect at (2, 4).
500
y = 4 Which of these is not a function? y = -2x + 7 y = 5x - 1 x = 6 y = -2/3
x = 6
