In the graph of a curve,the vertical intercept is the:

A) value of the y-variable when the value of the x-variable is equal to zero.
B) change in the y-variable between two points divided by the change in the x-variable between those same two points.
C) value of the y-variable when the value of the slope is equal to zero.
D) value of the x-variable when the value of the y-variable is equal to zero.

Vertical Intercept

The point at which a curve hits the vertical axis; it shows the value of the y-variable when the value of the x-variable is zero.

X-variable

A variable representing an unknown or unspecified quantity in mathematical functions or equations.

Y-variable

In a coordinate system, it represents the dependent variable, whose value depends on that of another variable (usually the x-variable).
