How can a linear function in two variables be graphed? Choose the best explanation.

• A linear function in two variables cannot be graphed.

• A linear function in two variables can be graphed by subtracting the largest numbers from the smallest ones, plotting the differences, and then drawing a line through those points.

• A linear function in two variables can be graphed by finding the slope and then guessing where the intercepts should go by drawing a line that might go through them.

• A linear function in two variables can be graphed by finding the x-intercept and the y-intercept and then drawing a straight line that passes through them.

What are the
x-intercepts of the function
f(x)= (x - 2)(x + 3)?

• x = - 2 or x = 3

• x = 2 or x = -3

• The are no real roots

• x = 2 or x = 3

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)
