Standard Form to Slope Intercept Form

The slope is -6.

Given the equation: y = 6 - 6x What is the slope?

The y-intercept is where the line crosses the y-axis.

How do you identify the y-intercept of a line by looking at the graph?

-2

What is the slope of a line parallel to: y = -2x + 5

-3

What is the slope of a line parallel to: y = -3x - 3

b = 7

What is the y-intercept of the following line: y = 7 + 5/3x

The lines will never cross and their slopes are the same!

What is true about parallel lines?

y = -2/3x - 2

Write an equation for the given line in slope-intercept form (solved for y).

x = 2

x = 2

3x - 4y = 8

y = 3/4x - 2

5x - 2y = -16

y = 5/2 x + 8

5x - 7y = -21

y = 5/7 x + 3

7x - 16y = -8

y = 7/16x + 1/2

x = 4

x = 4

9x - 2y = 10

y - 9/2x - 5

2x + 4y = -12 (Write in slope-intercept form)

y = (-1/2)x - 3

x + 5y = 12 (Write in slope-intercept form)

y = (-1/5)x + 12/5

3x + 2y = 6 (Write in slope-intercept form)

y = (-3/2)x + 3

4x + 7y = 6 (Write in slope-intercept form)

y = (-4/7)x + 6/7

5x + 3y = -8 (Write in slope-intercept form)

y = (-5/3)x - 8/3

8x + 3y = -15 (Write in slope-intercept form)

y = (-8/3)x - 5

3x - 6y = 9 (Write in slope-intercept form)

y = (1/2)x - 3/2

x - 3y = -9 (Write in slope-intercept form)

y = (1/3)x + 3

x - 6y = -12 (Write in slope-intercept form)

y = (1/6)x + 2

5x - 4y = 7 (Write in slope-intercept form)

y = (5/4)x - 7/4

11x + 3y = -12

y = -11/3x -4

3x + 4y = -32

y = -3/4x - 8

4x + 7y = 35

y = -4/7x + 5

4x + y = -2 (Write in slope-intercept form)

y = -4x - 2

5x + y = -2

y = -5x - 2

13x - 2y = 12

y = 13/2 x - 6

7x - y = 13 (Write in slope-intercept form)

y = 7x - 13
