Writing Equations in Slope-Intercept Form

Slope-intercept form of a line is expressed as ( y = mx + b ), where ( m ) is the slope and ( b ) is the y-intercept.

Key Equations

( y = 5x - 3 )
- Slope: 5; y-intercept: -3
( y = -6x - 2 )
- Slope: -6; y-intercept: -2
( y = 3x - 12 )
- Slope: 3; y-intercept: -12
( y = x + 2 )
- Slope: 1; y-intercept: 2
( y = -2x + 7 )
- Slope: -2; y-intercept: 7
( y = 7x + 1 )
- Slope: 7; y-intercept: 1
( y = -4x )
- Slope: -4; y-intercept: 0
( y = 8 )
- Slope: 0; y-intercept: 8 (horizontal line)
( y = -x + 2 )
- Slope: -1; y-intercept: 2
( y = x )
- Slope: 1; y-intercept: 0 (passes through origin)
( y = -x )
- Slope: -1; y-intercept: 0 (passes through origin)
( y = x - 2 )
- Slope: 1; y-intercept: -2
