Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3

• y = (5/3)x + 9

• y = (5/3)x + 3

• y = (3/5)x + 3

Which of these represents standard form of a linear equation?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

• y=kx

Write in standard form.
2x - 2 = 6y

• 2x - 6y = 2

• x - 3y = 1

• 2x + 6y = -2

• 2x - 6y = -2

Write in standard form.
y = -3x + 5

• y = -3x + 5

• 3x + y = 5

• 3x - y = 5

• -3x + y = -5

What is the slope intercept form of this equation? 
3x - 4y = 24

• y = 3/4 x + 6

• y = 3/4 x - 6

• y = -3/4x + 6

• y = -3/4x - 6

Determine the equation, in point-slope form, that best models the following story:

Maddie designed a website for the group Disturbed. On day 10 the site had 5000 hits. It started to receive 1000 hits per day afterwards.

• y- 10 = 1000(x-5000)

• y - 5000 = 10 (x-1000)

• y - 10 = 5000(x - 1000)

• y - 10 = 1000(x - 5000)

What does "m" represent in y=mx+b?

• y-intercept

• slope

• macaroni

• nothing
