Linear Functions Flashcards
1
Q
The value of m
A
- m = rise/run = (x1 - x2)/y1 - y2)
- (x1, y1) and (x2, y2) are coordinates
2
Q
Linear Equation
A
y = mx + b
3
Q
Point-Slope Equation
A
y - y1 = m(x - x1)
4
Q
Standard Equation
A
- Ax + By + C = 0
- a ∈ W
5
Q
Conversions Between Equations
A
- m = -A/B
- b = -C/B
6
Q
Perpendicular Slopes
A
m = -1/m
7
Q
