Slope Intercept Form from Equations

Write a formula in slope-intercept form for a function that has a constant rate of change of -7 and passes through the point (0, 5.8).

• y = -7x + 5.8

• y = 5.8x - 7

• y = 7x + 5.8

• y = 7x - 5.8

My water bottle started with 32 ounces of water in it and I drank 8 ounces per hour. Write a formula for the amount of water remaining.

• y = 8x + 32

• y = -8x + 32

• y = 8x - 32

• y = 32x + 8

Write the equation of the graph.

If m = 3 and b = 6, what is the correct slope intercept equation?

• y=3-6

• y=3x-6

• y=3x+6

• y=6x+3

Given the slope of 3/4 and a y-intercept of -2; write an equation of the line in slope-intercept form.

• y = -2x + 3/4

• y = -3/4 x - 2

• y = 3/4 x - 2

• y = -2x - 3/4

Write the equation of the graph.

A swimming pool had a leak. After 2 hours it had 800 gallons in it and then after 6 hours it had gone down to 600 gallons. Which equation represents this situation?

• y = - 50x + 900

• y = - 200x + 900

• y = 200x

• y = 4x
