Find the y-intercept.

To find the y-intercept of a linear equation, you need the equation itself. The y-intercept is the point where the line crosses the y-axis, which occurs when the x-coordinate is zero.

If you have an equation in slope-intercept form (y = mx + b), the value of b is the y-intercept. For example, if you have the equation y = 2x + 3, the y-intercept is 3.

If you have an equation in standard form (Ax + By = C), you can solve for the y-intercept by setting x = 0 and solving for y. For example, if you have the equation 2x - 3y = 6, substitute x = 0 to get -3y = 6. Then solve for y by dividing both sides by -3, which gives you y = -2. The y-intercept in this case is -2.

So, to find the y-intercept of a linear equation, look for the constant term in the equation or substitute x = 0 and solve for y.
