1. Slope
A number that represents the rate of change in y for a unit change in x
∆y y2 – y1
∆x x2 – x1 = 2 3
Slope =
Rate of Change

2. Is where x = 0 and located where the graph crosses the y-axis
y = 4x + 2
2x + 3y = 12
y-int: x = 0
2(0) + 3y = 12
y = 12
y = 4
y-int: (0,4)
y-intercept

3. Is where y = 0 and located where the graph crosses the x-axis
2x + 3y = 12
x-int: y = 0
2x + 3(0) = 12
2x = 12
x = 6
x-int: (6,0)
x-intercept

4. the set of all possible x-values
Domain
the set of all possible x-values
- 0 < x < 0
Left-Most
Right-Most

5. the set of all possible y-values
Range
the set of all possible y-values
- 0 < y < 0
Lowest
Highest

6. An equation with 2 or more variables
Literal Equation
Examples:
y = mx + b
F = C + 32
A = LW
V = LWH
A = 1 2 bh
A = πr2

7. Conversion Factor 15840 ft 1 mile 1hr 6 hrs 5280 ft 60 mins
1 mile = 5280 feet
1 mile = 1760 yards
1 hour = 60 minutes
1 gallon = 16 cups
Changes a value to a different form but still obtains original value
Convert to miles per minute
15840 ft 1 mile hr
6 hrs ft mins
