Final answer:
The linear function y = 3x + 4 has the greatest y-intercept, which is 4. It surpasses the y-intercepts of the other provided linear functions.
Step-by-step explanation:
To determine which linear function has the greatest y-intercept, we need to look at the constant term in each function, when written in the form y = mx + b, where m is the slope and b is the y-intercept. For the given linear functions:
- y = 6x + 1 has a y-intercept of 1.
- A line through points (0, 2) and (5, 0) can be represented by the equation y = -2/5x + 2, with a y-intercept of 2.
- A line through points (1, 2) and (0, -3) can be represented by the equation y = 5x - 3, with a y-intercept of -3.
- y = 3x + 4 has a y-intercept of 4.
Therefore, the function with the greatest y-intercept is y = 3x + 4, as the y-intercept is 4 which is higher than the other given intercepts.
