Name the Slope
y = -2x + 4
m = -2
y = -x + 5
b = 5
Evaluate y = -3x +4 if x = 5
y = -11
A line has a slope of -2 and a y-intercept of -6
y = -2x -6
Probability of getting an even number on a die (simplify!!)
1/2
A line passes through the points (7, 10) and (9, 16)
m = 3
y = 10x
b = 0
Evaluate y = 2x - 10 if x = -9
y = -28
Any line perpendicular to y = -2/3x - 4
y = 3/2x + _____
Find the mean:
8, 7, 15
10
A line is parallel to
y = -4x + 7
m = -4
10x -2y = 16
(Remember to get equation in y=mx+b form first!)
b = -8
The money Leah spends at an amusement park is represented by y = 2x + 10, where x is the number of tokens she bought, and y is the total amount of money she spends.
If she buys 4 tokens, how much money does she spend?
$18
