8.) A linear equation has more than one y-intercept. What can you conclude about the graph of the equation??


Help Idk this question!!

Please help me it is one of my math homework questions!!

i'm not sure if this is a trick question, but the definition of a linear function prevents the function from having more than one y-intercept. x-values can't be shared in a function; there is a unique x value for every y value. at the y-axis, the value of x is 0. two y-intercepts would mean that x would be 0 for TWO points on the linear function, which doesn't pass the vertical line test and, therefore, isn't a function.

a graph CAN, however, have more than one x-intercept. the line y = 0, which passes the vertical line test and sits directly on top of the x-axis, has infinitely many x-intercepts and it is still a linear function.

Answer:

Step-by-step explanation:

A straight line can either have 1 y-intercept or infinitely many y intercepts. The only case in which there are infinitely many y-intercepts is when the line represents the y-axis itself. On y-axis, x is always 0. So the line that represents the y-axis is the line x=0. However, it is not a linear equation. In short, only the line representing y-axis has more than 1 y-intercepts. There cannot be such a linear equation(function).
