x=2
Write an equation in point slope form for a line that passes through the point (-4,2) and m=-2.
y-2=-2(x+4)
What are the 3 methods we learned to solve systems of equations?
Substitution, Elimination, and Graphing.
Write an equation that represents a line passing through the point (5,-2) that is parallel to the y-axis?
x=5
What sport did Ms. Bearden play all 4 years of high school?
Basketball
What is the slope AND y-intercept of the following function? 2x+5y=20
m=-2/5 & b=4
What does it meant to have a slope that is parallel to a function and what about perpendicular?
The functions would have the same slope for parallel. For perpendicular, the functions would have opposite flip slopes.
Solve. -3(4r – 8) = -36
r=5

A student is ordering books. She can choose any combination of fiction and non-fiction for her library, and she does not want to spend $100 or more. If fiction books (x) cost $9 each and non-fiction books (y) cost $4 each, write an inequality that represents all possible combinations of fiction books and y non-fiction books that the student can buy

The NHS club sent its members on four field trips during the school year. The number of buses needed to transport the members on each trip is a function of the number of members who went on each trip. This function consists of only the ordered pairs (49, 3), (51, 4), (72, 5), and (101, 6). What is the domain for this situation?
{49, 51, 72, 101}
What is Ms. Bearden's favorite sport to play right now?
Sand Volleyball
The value of y varies directly with the value of x. If x=8 when y=6, then what is the value of y when x=-2?
y=-3/2
