TL;DR

Find x-intercept by setting y=0, y-intercept by setting x=0, plot points, connect to graph line.

Transcript

hi everyone in this problem we have to use the intercepts to graph this equation so we'll start by finding the x intercept so to find any intercept you set the other variable equal to zero so to find the x intercept we basically just set y equal to zero in this equation so this is two x plus three times zero plus six and that's equal to zero three ...

Questions & Answers

Q: How do you find the x-intercept of an equation?

To find the x-intercept, set y=0 in the equation and solve for x. The resulting point is where the line crosses the x-axis.

Q: What is the process for finding the y-intercept?

To find the y-intercept, set x=0 in the equation and solve for y. This gives the point where the line intersects the y-axis.

Q: After finding both intercepts, what is the next step in graphing the equation?

Plot the x and y intercepts on the coordinate plane, then connect them with a straight line to graph the equation.

Q: How does using intercepts help in graphing equations?

Finding intercepts simplifies graphing by providing key points on the line, allowing for accurate representation without additional calculations.
