Slope-Intercept Form Review

Identify the slope. (m = rise / run)

Identify the slope. (m = rise / run)

Identify the slope of (-13, -17) and (8, 12)

Identify the slope of (-11, 10) and (-15, 13)

Identify the slope of (8, -3) and (-2, 16)

Identify the slope of (8, -3) and (-2, 16)

Rewrite this equation in slope intercept form (y = mx. + b):

x + y = -15

• x = -y -15

• y = -x + 15

• y = -x - 15

• y = x - 15

Rewrite this equation in slope intercept form (y = mx. + b):

9x + 3y = -6

• 3y = 9x -6

• y = -3x -2

• y = -9x - 6

• y = -3x +2

Rewrite this equation in slope intercept form (y = mx. + b):

6x - 2y = 10

• 2y = 6x - 10

• y = -3x - 5

• y = 3x - 5

• y = -3x + 5

Which equations have the same slopes?

(Hint: rewrite in slope-intercept form first)

• -3x + y = -4

• -6x + 3y = 6

• -2x + y = -4

• -10x + 12y = 9
