Math Problem Statement

whats the answer

Which statement is true about the y-intercepts of Function A and Function B?

Solution

To determine which statement is true about the y-intercepts of Functions A and B, let's examine each function.

Function A

The graph shows a line crossing the y-axis at y=1y = 1. Therefore, the y-intercept of Function A is 11.

Function B

Function B is given by the equation y=2x3y = 2x - 3. This equation is in the slope-intercept form y=mx+by = mx + b, where bb represents the y-intercept. In this case, the y-intercept bb is 3-3.

Comparing the Y-Intercepts

  • The y-intercept of Function A is 11.
  • The y-intercept of Function B is 3-3.

Since 1>31 > -3, the y-intercept of Function A is greater than the y-intercept of Function B.

Conclusion

The correct statement is: "The y-intercept of Function A is greater than the y-intercept of Function B."
