Linear Equations
What is the slope of the line represented by the equation y= 3x + 2
2
Solve for x: 3x − 4= 8
x= 4
What is the mean of the numbers 6, 8, and 10?
8
What is a reflection in geometry?
A reflection is a flip of a figure over a line, creating a mirror image.
Solve for x: 2x + 5 =15
x=5
What is the first step to solving 5x + 10=30?
Subtract 10 from both sides
Find the median of the set: {3, 7, 5, 9, 2}

How many degrees is a full rotation?
360 Degrees
What is the equation of a line that passes through the points (2, 3) and (4, 7)?
y= 2x - 1
Solve for x: 2(x−3)=8
x=7
What is the mode of the set: {2, 3, 4, 4, 5, 6, 6, 6}?

Describe what happens to a shape during a 90-degree rotation clockwise.
A shape rotated 90 degrees clockwise turns to the right, changing the coordinates from (x,y) to (y,−x).
Graph the equation y − 4= 2(x+1)
y= 2x + 6, slope is 2 and y-intercept is 6
If 4x + 7 =3, what is the value of x?
x= -1

What is the rule for reflecting a point across the y-axis?
Reflecting across the y-axis → (x,y) → (−x,y)
What is the y-intercept of the line represented by the equation 4x − 2y=8
-4
Solve for x: 7 − 2(x+1)=1
x = 2
If the numbers are {1, 2, 2, 3, 4, 4, 5}, what is the mode?
2 and 4
Explain the transformation that occurs when a shape is translated 5 units up and 3 units to the right.
A translation 5 units up and 3 units to the right means each point moves to (x+3, y+5)
