• Negative

• 0

• Undefined

What is the correct slope-intercept form?

• y = mx + b

• y = mb + x

• y = x

• y = -mx + b

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

• y = -2x - 5

• y = 2x - 5

• y = -2x

• y = -1/2x - 5

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

• y = 1/2x

• y = 2x + 1

• y = -2x - 2

Stephanie owes her mom $80 for a recent trip to the mall. She plans to payback $15 a month until it is paid back. Write an equation in slope-intercept form that relates the amount she owes, y, to the amount of months, x.

• y = 15x - 80

• y = 15x + 80

• y = -15x + 80

• y = -15x - 80

At 10:00 pm, there was already 8.6 inches on the ground. If it is to snow 2 inches per hour after, what equation could be used to model the situation after x amount of hours.

• y = 2x + 8.6

• y = 2x - 8.6

• y = -2x + 8.6

• y = 1/2x + 8.6

What is the graph's equation?

• y = 4/3x - 1

• y = -4/3x - 1

• y = 3/4x + 1

• y = - 3/4x - 1

• y

• m

• x

• b

What is the equation of a line when m = -7 and b = -8?

• y = -7x + 8

• y = -7x - 8

• y = 7x - 8
