1. All horizontal lines have the same slope.
2. A line with a slope of 1 always passes
through the origin (0,0).
3. Two lines may have the same slope.
4. The slope of a line that passes through
Quadrant III must have a negative slope.

9. Writing Equations in Slope-Intercept Form
What is the slope and y-intercept of this line?
4y - 12 = 3x
Needs to be put into slope-intercept form.
Solve for y.
4y - 12 = 3x
4y = 3x + 12
+ 12 + 12
Now divide each term by 4 4y = 3x + 12
4 4 4
y = 3x + 3

10. Converting an equation to slope-intercept form

11. WHITEBOARD PRACTICE
Please put these equations into slope/intercept form, then give the slope and y-intercept.
y = 3 - x m = -1 b = 3
2y = 4x + 8 m = 2 b = 4
6x + 3y = 4 m = -2 b = 4/3
y + 1/3x = -2 m = -1/3 b = -2
y/2 - 7x = 0 m = 14 b = 0
4x + y/4 = 5 m = -16 b = 20
6y - 2g = 4x m = 2/3 b = g/3
y = mx + b
y = mx + b
y = mx + by = mx + by = mx + b
y = mx + b
y = mx + b
