Equations of this form have graphs that are vertical or horizontal lines.In equations #5 and #6, both x and y are on the same side of the equation. These two equations are of the form Ax+By=CAx+By=C . We substituted y=0y=0 and x=0x=0 to find the x- and y- intercepts, ...
Using Intercepts to Graph Lines You can use intercepts to graph linear equations. Once you have found the two intercepts, draw a line through them. Let’s do it with the equation 3y+2x=63y+2x=6. You figured out that the intercepts of the line this equation represents are (0,2)(0,2...
There are three special quantities associated with straight lines and their graphs. One is the slope of the line. The other two are the x- and y-intercepts of the graph. The idea behind developing what is called the slope of a line is to find a number that can be associated with the...

2. Graph a straight line by finding itsx- andy-intercepts. 3. Graph horizontal and vertical lines. Graphing a Linear Equation by Plotting Three Ordered Pairs We have seen that the graph of an ordered pair is a point. An ordered pair can also be a solution to a linear equation in two ...
This calculator is the Swiss army knife of the graphing calculator world. You can use this TI-89 to perform all of the calculations that other graphing calculators can. These functions include calculating complicated lines of equations, square roots, solve for X and Y intercepts, graph functions...
You can see the difference in how the graph crosses thex-axis. If it crosses in the manner that you're used to, from graphing straight lines, then the zero is of multiplicity one. If, on the other hand, the graph "flexes" or "flattens out" to some degree when it goes to cross...
5.3: Slope-Intercept Form Quick Graphs Using Slope-Intercept Form X and Y Intercepts. Systems of Equations Solving by Graphing. Lesson 4.4 Objective: To graph a line on a coordinate plane only using the slope and the y-intercept. Essential Question: How can I graph an equation without. ...
REMEMBER: Asolutionto a system of equations is the point where the lines intersect! Prerequisitesfor completing this unit:Graphing using slope intercept form. We will begin graphing systems of equations by looking at an example with both equations written in slope intercept form. This is the easie...
