The formula to calculate the y-intercept is:
\[ b = y - mx \]
Where:
Let's say the slope is 2, and the point is (3, 6). Using the formula:
\[ b = 6 - 2 \times 3 = 6 - 6 = 0 \]
So, the y-intercept is 0.
The y-intercept is the point where the line crosses the y-axis. It is the value of \( y \) when \( x \) is 0.
