Which letter is the slope?
y=mx+b
m
100
What is the solution of this system?
(3,-1)
100
How would you say this inequality in words?
6x>=-7
"6x is greater than or equal to -7"
100
If you graphed the inequality below, would you shade below it or above it?
y>=3x+4
above

Which Timberwolf just got traded to the New York Knicks?
Karl Anthony Towns
or
KAT!
200
What is the formula for slope?
(rise)/(run) or (y_2-y_1)/(x_2-x_1)
200
Why should you use elimination for this system?
3x+9y=2
2x-9y=8
Because if you add the equations the 9y and -9y will cancel out (eliminate)

Write the inequality represented by this number line. Use x for your variable.
x>3
200
True or False: the point where the lines intersect is part of the solution.
False
200
Who's in the World Series right now?
LA Dodgers vs. the New York Yankees
300
Put this equation in slope-intercept form
10=5x-4y
y=5/4x-5/2
300
Why should you use substitution for this system?
5x+6y=20
x=7-2y
Because the x is already by itself (isolated) in the second equation.
