Study Notes
Slope-Intercept Form
- The slope-intercept form of a line that passes through (3, 4) with a slope of -2 is y = -2x + b, where b is the y-intercept.
Equations of Lines
- The equation of the line that passes through (1, 5) and (4, 11) is y = 2x + 3.
- The equation of the line through (0, 2) with slope $-\frac{1}{3}$ is y = $-\frac{1}{3}$x + 2.
- The equation of the line with slope 4 and passes through (-3, 2) is y = 4x + 14.
- The equation of the line through (5, 3) with a slope of 0 is y = 3.
