To find y-intercepts in linear equations, you can use these simple methods:
Set x to zero: If you have a linear equation like (y = mx + c), just replace (x) with (0). The value you find for (y) is the y-intercept.
Example: Take the equation (y = 2x + 3). When you set (x = 0), you get (y = 3). So, the y-intercept is the point (0, 3).
Look on a graph: On a graph, the y-intercept is where the line meets the y-axis.
Use a table of values: Make a table by choosing different (x) values, including (0).
By practicing these methods, you can easily find y-intercepts!
