Can a horizontal line have an x-intercept? What if the line passes through the origin? Explain.

Answer:
B.A horizontal line never have an x- intercept.the x- intercept is defined as the point at which a line crosses the x- axis.
Step-by-step explanation:
We have to find that a horizontal line can have an x- intercept and what happened when the line passes through the origin.
X-intercept: It is defined as the value of x at which the graph cut the x- axis.
No, a horizontal line can not have x- intercept.Because the x -intercept is defined as the point at which a line crosses the x- axis.
When a horizontal line passes through the origin then it coincide the horizontal line.

The equation is y = 63/x
And y = 3 when x=21
Step-by-step explanation:
When y varies inversely with x, The inverse proportion is given by:
y ∝1/x
When the proportionality symbol is removed, a constant of proportionality is introduced
Putting y = 7 and x = 9
So,
Putting x =21
Hence,
The equation is y = 63/x
And y = 3 when x=21
