Linear equations are called "linear" because they make a "blank" line when we graph them.
straight
In a system of equations: The number of "blank" should be equal to the number of equations.
variables
The cube root of a negative number is "positive" OR "negative"?
negative
What is the third side of the right triangle with legs of lengths 3 and 4?
5
Name three types of transformations.
Rotation, dilation, reflection, translation,
What is slope-intercept form?
y=mx+b
What is the only case where there is no solution to a system of equations?
When the lines are parallel.
65 = 6x ยท 64 ; What does x equal?
x=1
What is the Pythagorean theorem in terms of b?
What is the difference between two shapes that are congruent and two that are similar?
Corresponding parts of congruent shapes are equal vs. corresponding parts of similar shapes are in a fixed ratio with each other.
Slope is "blank"/"blank"
Change in Y/ Change in X
How do you solve a system of equations with graphing?
Graph both lines --> the intersection point is the solution.
write 1,230,000 in scientific notation
1.23 x 106
The pi r2 comes from finding the area of the "base circle" and the h comes from multiplying it on the height b/c the cylinder is that circle "stacked".
If you dilate a shape what are you doing to it?
True or False: A function allows for more than one y value for any given x value.
False
Why are systems of equations useful/when would you use them?
When solving for more than 1 variable.
True or False: Pi is a rational number.
False

When classifying numbers, what category do integers and whole numbers fall under?
Rational Numbers
How do you use the Pythagorean theorem to find the area of an isosceles triangle?
Drop an altitude then find the area of one of the right triangles created and multiply it by two.
In geometry, a "blank" moves a thing up and down or left and right.
