A triangle has a vertex at A(4, -3). If you translate it 5 units left and 2 units up, what are the new coordinates of A’
(-1-1)
what is slope intercept form?
y=mx+b
(6,7) (8,8) (5,9) Do these coordinates represent a function why or why not?
Yes, these coordinates represent a function because every input (x) has exactly one output (y).
What is a Linear
straight line
Simplify the expression: (x³ * x⁷) When multiplying terms with the same base, keep the base and add the exponents.
answer: x³⁺⁷=x¹⁰
Point C(3, 8) is rotated 90° clockwise around the origin. What is the image?
(8,-3)
what do the letters m and b in slope interspent form stand for?
m=slope b=y intercept
Which variable is the domain?
x variable
As you study more hours your test scores go up the dots go up from the line what kind of association is this?
positive association
Simplify and write with a positive exponent: 4-3
1/64
Use the coordinates (6,-7) to rotate 90 degrees CW
(6,-7)
what is positive slope?
when the graph goes up from right to left
What test is done to check if a line is a function or not?
vertical line test
What is the name of the starting line drawn through the center of the dots?
line of best fit
Evaluate the expression: (5⁴)*(2³)⁰)
1
Whats the rule to reflect over the x-axis?
(x,-y)
how do you find slope from a graph?
delta y/delta x
This is the volume formula for what shape? 𝑉 = ⅓ 𝜋 r3
sphere
A graph compass height and eye color the dots are all over the page with no line. What kind of correlation is this?
no correlation
what is any base raised to the zero power
What's a dilation?
a change to a figure which makes it either larger or smaller.
Find the slope of the line passing through (19, -16) and (-7, -15)
-1/26
Find the volume of a cylinder with radius 5 in and height 4 in.
314.16 𝜋in³
