Which function has a y-intercept of 3?

1 answer:

3 0

If you have choices, you should list them. If you are just asking about any example, then here are some.

y = a*x + 3 ; the value of a can be any real number.

- 3x + y = 3
2y + 4x = 6

ny = ax + 3*n When you divide through by n, you get
y = a/n * x + 3n/n
y = ax/n + 3

Answers: A , B , and D are correct.
________________________________________________________
The following statements are true and correct:
____________________________________________________
[A]: y is a function of x .
____________________________________________________
[B]: The graph of the relationship is a line.
____________________________________________________
[D]: When the input is -2, the output is 3.

Note:

Choice: [C]: "When the input is -3, the output is 4 ." → is INCORRECT.

Note: When the input is -3, the output is "4 <span>⅓";
that is, when x = -3, y = 4 </span>⅓ .
_____________________________________________________
Choice: [E]: "The y-intercept of the relationship is: (0,1)." → is incorrect.

Note: The y-intercept refers to the value of "y" where the line crosses the "x" axis. From the equation; and form the graph, we see that the y-intercept is: "⅓" ; or, "(0, ⅓)" .
