How do you find the Y intercept given an equation?

To find the Y-intercept of an equation, set the value of ( x ) to 0 and solve for ( y ). In a linear equation of the form ( y = mx + b ), the Y-intercept is simply the value of ( b ). For other types of equations, substitute ( x = 0 ) and compute the resulting value of ( y ). This point, where the graph intersects the Y-axis, will have coordinates ( (0, y) ).
