Point-Slope Form Overview

Represents linear equations in the format y = mx + b, where m denotes the slope and b is the y-intercept.
The slope represents the steepness of the line and direction (positive or negative).

Specific Linear Equations

y = -1/2x + 4
- Slope: -1/2
- Passes through the point (2, 3).
y = 4x + 8
- Slope: 4
- Passes through (-1, 4).
y = -5/2x + 2
- Slope: -5/2
- Passes through the y-intercept (0, 2).
y = -1/2x + 9
- Slope: -1/2
- Passes through multiple points: (-4, 6) and (-2, 5).
y = 5x - 2
- Slope: 5
- Passes through prominent points: (-1, -7) and (1, 3).
y = 1/4x - 2
- Can be expressed in point-slope form as: y + 5 = 1/4(x + 2).
y = 2x + 6
- Also can be rewritten as: y = 2(x + 3).
y = -3x + 5
- Expressed as: y - 8 = -3(x + 1).
y = -1/5x - 3
