What is the x-intercept of the following graph?

• 0

• 6

• -4

• 2/3

The graph of linear function f passes through the point (-5,8) and has a slope of -4. What is the zero?

hint: use point slope to write the equation in slope intercept form. Then find where the line crosses the x-axis

• -4

• -3

• -12

• -8

A paper airplane was thrown from the top of a tall builidng. The height of the paper airplane above the ground can be found using the function y = -1.5x + 60, where x is the time in seconds the airplane has been in the air. How many seconds did it take the paper airplane to reach the ground? (Hint: you're looking for the x-intercept)
