• (6, 0)
• (0, 4)
• (-1, 3)
• (2, 0)

Multiple Choice

True or false:

• True
• False

Multiple Choice

Which ordered pair could represent the x-intercept of a function.

• (0, 4)
• (4, 4)

• None of these.

Multiple Choice

True or false:
The y-intercept of a function ALWAYS occurs where y is equal to zero.

• True
• False

​More notes.... (write this down, please.

• To find the x-intercept, set y = 0 and solve your equation for x.

• To find the y-intercept, set the x = 0 and solve your equation for y.
