What is the slope-intercept form of the equation

 with a slope of 5 and a y-intercept of -8?

 

y=-8x+5

y=8x-5

5x - y = -8

y = 5x -8

Which equation is graphed below?

2y - x = 10

2x + y = -5

2x - y =5

2y + x = -5

Which is an equation of the line that passes through

(2, -5) and (6, 3)?

y = ½x - 6

y = 2x + 12

y = ½x

y = 2x - 9

What is an equation of the line through (0, -3)

with slope 2/5 ?

-5x + 2y = 15

-5x - 2y = -15

2x - 5y = 15

-2x + 5y = 15

Which is an equation of the line with slope of -3

and a y-intercept of 5?

y = -3(x +  5)

y - 5 = 3x

 3x + y = 5

y = 5x - 3

What is the equation of the line through (-2, -3)

with a slope of 0?

x = -2

y = -3

-2x - 3y = 0

-3x + 2y = 0

Find the slope-intercept form of the equation of

the line that passes through (-5, 3) and is parallel

to 12x - 3y = 10

y = -4x - 17

y = 4x - 13

y = -4x + 13

y = 4x + 23

If line x has a slope of -⅜, what is the slope of any line

perpendicular to x?

-⅜

8/3

-8/3

When are 2 lines parallel?

when the slopes are opposite

when the slopes are equal

when the slopes are positive

when the product of the slopes is 1

Write y - 3 = ⅔ ( x - 2) in standard form.

2x - 3y = 5

y = ⅔x + 5/3

-2x + 3y = -5

 2x - 3y = -5
Write y - 1 = 2 (x - 3/2) in slope-intercept form.

2x - y = 2

½y + ½ = x

y = 2x - ½

y = 2x - 2

y=-3/7x-2/7

y=-3/7x-1/8

y=3/7x-1/8

y=3/7x-2/7
