To find the x-intercept of an equation, which variable is set to zero?
ASet none to zero
BSet y to zero
CSet x to zero
DSet both to zero
Answer & Solution
Correct answer: B. Set y to zero
1. An intercept is where the line meets an axis.
2. The x-intercept lies on the horizontal axis.
3. To find the x-intercept, let y equal 0.
4. Setting the other variable to zero gives the y-intercept.
