Learn how to find the x-intercepts and y-intercepts of a Linear Function and Quadratic Functions. Solve for x and y intercepts and learn to plot them in the Cartesian Plane.
X and Y-intercept are useful to find the slope, equation of a line, and also to find the area made by the line with the coordinate axes. Let us learn more about how to find the x and y-intercept, the graph, and the uses, with the help of examples, FAQs.
an x-intercept is a solution to the equation when the y-value has been set to zero, and; a y-intercept is a solution to the equation when the x-value has been set to zero. This understanding of intercepts as solutions to equations allows us to establish the algebraic process for finding intercepts. How do you find x-intercepts and y-intercepts?
Y Intercept: where the graph of an equation crosses the y-axis. To find the intercepts: When you want the x intercepts (x,0): Set y=0 then solve for x. When you want the y intercepts (0,y): Set x=0 then solve for y. Example: Find the intercepts of y = x 2 − 4. x intercept: set y=0. 0 = x 2 − 4.
Find the X- and Y-Intercepts Using Algebra. When the equation is written in the slope-intercept form (\(y=mx+b\)), you can find the y-intercept by looking at the equation. The value of b is the y-intercept. This is because the y-intercept is when the x value equals 0.
11 Οκτ 2024 · To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis.
20 Οκτ 2024 · To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.
