Finding X and Y Intercepts Quiz

What is the x-intercept of a line?

• The point where the line crosses the y-axis

• The point where the line crosses the x-axis

• The point where the line crosses both axes

• The point where the line does not cross any axis

If a line crosses the y-axis, what is the value of x at that point?

• x is equal to y

• x is equal to 0

• x is equal to -1

• x is equal to 1

In the substitution method, what do you substitute to find the x-intercept?

• Substitute 1 for y

• Substitute 0 for x

• Substitute 0 for y

• Substitute 1 for x

What is the x-intercept of the equation -2x = 20?

• x = -20

• x = 10

• x = -10

• x = 20

In the cover-up method, what do you do to find the y-intercept?

• Cover up the y variable

• Do not cover any variable

• Cover up the x variable

• Cover up both variables

What is the y-intercept of the equation 5y = 20?

• y = 5

• y = 4

• y = 20

• y = -4

In the cover-up method, what happens to the variable you cover?

• It is ignored

• It is set to 1

• It is set to 0

• It is doubled

What is the x-intercept of the equation 3x = 16 using the cover-up method?

• x = -16/3

• x = 16/3

• x = 3/16

• x = 16

What is the y-intercept of the equation -4y = 16?

• y = 16

• y = 4

• y = -4

• y = -16

Why is the cover-up method considered easier by some?

• It requires no calculations

• It involves fewer steps

• It uses both variables

• It provides exact answers
