Slope
Rise = 4
Run = 5
What is the slope?
What is the name of a transformation where the shape slides to the left?
translation
y = 2x -7
2
Is the set of ordered pairs a function? How do you know?
(2, 3) (4, 3), (5, 3), (8, 3)
yes, each input (x-value) only has one output (y-value)
32 + (-9)
Rise = 0.25
Run = 1
What is the slope?
0.25/1 or 1/4
What is the name of a transformation where the shape flips over the x-axis?
reflection
What is the y-intercept?
y = 5x -15
-15 or (0, -15)
Is the set of ordered pairs a function? How do you know?
(2, 2) (4, -4), (5, 7), (2, 3)
No, the input 2 has two outputs, 2 and 3
7 * (-6)
-42
What is the slope?
y = 3x + 2
3 or 3/1
What is the name of a transformation where the shape turns around a given point?
rotation
Write an equation in slope-intercept form.
m = 6
b = 2
y = 6x + 2
What is a linear function?
It forms a straight line
What is 35 * 32 as a single power?
37
What is the slope between the two points?
(4,2) (2, 1)
2/1 or 2
What is the name of a transformation where the shape changes in size?
dilation
Write an equation in slope-intercept form.
slope = -4
y-intercept = 1.5
y = -4x + 1.5
Is y = -2x + 7 linear or nonlinear? How do you know?
It is linear because all equations in slope-intercept form are straight lines.
n4 = 64, n = ?
n = 4
What is the slope between the two points?
(5, 2) (6, 8)
6/1 or 6
(6,2) (10, 4) (-8, 6)
What would the new coordinates be if the shape was dilated with a scale factor of 1/2?
(3, 1), (5, 2), (-4, 3)
Write an equation in slope-intercept form.
slope = 2.3
y-intercept = -8
y = 2.3x - 8
Is y = 3x2 - 8 linear or nonlinear? How do you know?
It is nonlinear, because it is not in slope intercept form.
