What are the x-intercept and y-intercept of the line x + y = 4?

1. To find the x-intercept, let y = 0: x + 0 = 4, so x = 4, giving the point (4, 0). 2. To find the y-intercept, let x = 0: 0 + y = 4, so y = 4, giving the point (0, 4). 3. The intercepts are the points (4, 0) and (0, 4). _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 4 "Graphs", section 4.3 Graph with Intercepts_
