The point at which a line crosses the y-axis is called its y-intercept. It is generally in the form (0, y-int). To find this value, we can plug in 0 for x and then solve for y.
Steps:
y = 9(0)
y = 0
The point at which the graph of y = 9x crosses the y-axis is (0,0).
If there was a mistake somewhere, please do let me know! As I know that the answer I gave above is not on the list of answer choices. I would strongly recommend checking the equation in the original problem once more. :)
The graph crosses the y-axis at the point (0, 0)
None of the given options is correct
A graph crosses the y-axis at the point (0, y). This means that the graph will cross the y-axis when x = 0
To find the point where the graph crosses the y-axis, substitute x = 0 into the given equation
For the equation y = 9x
substitute x = 0 into the equation y = 9x to find the corresponding value of y
That is,
y = 9(0)
y = 0
Therefore the graph crosses the y-axis at the point (0, 0)
