Intercepts Quiz

What are intercepts?

• Points where the line intersects the x-axis

• Points where the line intersects the y-axis

• Points where the line intersects both the x-axis and y-axis

• Points where the line intersects neither the x-axis nor y-axis

How can you find the x-intercept of a line?

• Set y = 0 and solve for x

• Set x = 0 and solve for y

• Set both x and y equal to 1

• Set both x and y equal to 0

How can you find the y-intercept of a line?

• Set y = 0 and solve for x

• Set x = 0 and solve for y

• Set both x and y equal to 1

• Set both x and y equal to 0
