The y-intercept of a linear equation is the point on the y-axis at which the line cuts.
It could be found by plugging x = 0 in the given linear equation.
For example,
Consider 3x + 2y = 6. To find the y-intercept just plug x = 0 in the equation.
3(0) + 2y = 6
2y = 6
y = 3
(0, 3) is the y-intercept of the linear equation 2x + 3y = 6.
Note:
In the same way we can find the x-intercept by plugging y = 0 in the given linear equation.

How do you find system of linear equation in two variable?
By elimination and substitution
How do you find for the zero of a linear function?
If it is a linear function, it is quite easy to solve the equation explicitly, using standard methods of equation-solving. For example, if you have "y" as a function of "x", you would have to solve the variable for "x".
How do you find the x intercept on a linear equation?
At the x-intercept on the graph of the equation, y=0. Take the equation, set 'y' equal to zero, and solve the equation for 'x'. The number you get is the x-intercept.
What symbol will you find in every linear equation?
The equals sign ( = ). In fact it defines any equation, linear or not, since an equation is a statement that a particular value or term is equal to, so the result of solving, a second set of terms and operators. Any other symbols would be particular to the equation you have derived or are trying to solve.
How can you tell from a linear equation which direction it goes without graphing the equation?
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
