Final answer:
The y-intercept, or v-intercept, is the point where a plot line crosses the y-axis. It is represented by the 'b' in the equation y = mx + b. It tells you the value of 'v' when 'x' is equal to zero.
Step-by-step explanation:
The y-intercept, or the v-intercept in this context, is the point where a plot line crosses the y-axis. It is represented by the letter 'b' in the equation y = mx + b. The y-intercept tells you the value of 'v' when 'x' is equal to zero. For example, if the equation is y = 2x + 3, the y-intercept is 3. This means that when x = 0, y, or in this case v, is equal to 3.
