Name a point that the following line passes through:

y - 4 = -3(x + 10)

(-10, 4)

300
Rewrite this equation in slope-intercept form. x + y = -12
y = -x - 12

-10/8 which simplifies to -5/4
400

Write the point-slope form of a line that has a slope of 0 and passes through the point (-3, -4)

y + 4 = 0(x + 3)

y=-4

400
Rewrite the following equation in slope-intercept form. 3x + 6y = -18
y = -1/2x - 3
400

Find the x and y intercepts of the following line:
3x - 2y = 5

(5/3, 0)

(0, -5/2)

500

Find the slope of the following line:

-3x + 2y = 6

2y = 3x + 6

y = 3/2x + 3

m = 3/2

500

Write the equation of a line which passes through the following points: (-1, 3) and (3, 1)

m = (1 - 3)/(3 - (-1)) = -2/4 = -1/2

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

500

Rewrite the following equation in slope-intercept form. 4x - 8y = -24

-8y = -4x + 24

 y = 0.5x - 3 or y = 1/2x - 3
