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.
Here you will learn about how to find the y intercept from a straight line graph, including straight lines in the slope intercept form, y=mx+b and standard form, ax+by=c. Students will first learn about how to find the y intercept in 8 th grade math with their work with linear functions.
Y-Intercept of a Straight Line. Where a line crosses the y-axis of a graph. Just find the value of y when x equals 0. Example: In the above diagram the line crosses the y axis at y = 1. Example: Here the line crosses the y axis at y = −2.
The y-intercept of a function y = f(x) is a point where its graph would meet the y-axis and is obtained by substituting x = 0. Understand the y-intercept and its formula with derivation, examples, and FAQs.
In this example, we outline the general steps for graphing a line using slope-intercept form. Step 1: Solve for \(y\) to obtain slope-intercept form.
To find the \(y\)-intercept, set \(x = 0\) and solve for \(y\). This method of finding \(x\)- and \(y\)-intercepts will be used throughout our study of algebra because it works for any equation. To graph a line, find the intercepts, if they exist, and draw a straight line through them.
