Final answer:
To find the y-intercept on a graph, look for the point where the line intersects the y-axis. This point will have an x-coordinate of 0, and the y-coordinate is the value of y when x is 0. Alternatively, you can find the y-intercept using the equation of the line, where the y-intercept is the value of b in the equation y = mx + b.
Step-by-step explanation:
The y-intercept of a graph is the point where the line intersects the y-axis. To find the y-intercept, look for the point where the line crosses the y-axis on the graph. This point will have an x-coordinate of 0. The y-coordinate of the y-intercept is the value of y when x is 0.
For example, if the equation of the line is y = 3x + 2, the y-intercept is 2 because when x is 0, the value of y is 2.
Another way to find the y-intercept is to examine the equation of the line. The y-intercept is the value of b in the equation y = mx + b. So, if you have the equation given, you can determine the y-intercept directly.
