y = − 3 x − 2 y=-3x-2 y = − 3 x − 2

y = − 2 x + 2 y=-2x+2 y = − 2 x + 2

y = − 3 x + 2 y=-3x+2 y = − 3 x + 2

y = 2 x + 10 y=2x+10 y = 2 x + 1 0

A line includes the points (4, 8) and (5, 6). What is its equation in slope-intercept form?

y = − 2 x + 16 y=-2x+16 y = − 2 x + 1 6

y = − 3 x + 11 y=-3x+11 y = − 3 x + 1 1

y = − 2 x + 13 y=-2x+13 y = − 2 x + 1 3

y = − 3 x + 9 y=-3x+9 y = − 3 x + 9

A line includes the points (-2, 10) and (3, 5). What is its equation in slope-intercept form?

y = − 1 x + 8 y=-1x+8 y = − 1 x + 8

y = − 1 x + 6 y=-1x+6 y = − 1 x + 6

A line includes the points (7, 8) and (6, 4). What is its equation in slope-intercept form?

y = 4 x − 20 y=4x-20 y = 4 x − 2 0

y = 2 x − 6 y=2x-6 y = 2 x − 6

y = 2 x + 18 y=2x+18 y = 2 x + 1 8

y = 4 x − 16 y=4x-16 y = 4 x − 1 6

A line includes the points (3, 10) and (6, 11). What is its equation in slope-intercept form?

y = 1 3 x + 9 y=\frac{1}{3}x+9 y = 3 1 x + 9

y = 1 3 x − 7 y=\frac{1}{3}x-7 y = 3 1 x − 7

y = 1 2 x + 5 y=\frac{1}{2}x+5 y = 2 1 x + 5

y = 1 2 x − 4 y=\frac{1}{2}x-4 y = 2 1 x − 4
