Your slope was given to you, so where you see m, use 2. It is simple to find a point because we just need ANY point on the line.
The variable m is the slope of the line. Note also that it is useful to pick a point on the axis, because one of the values will be zero. Now we know the slope m is -2 because that was given to us. As you can see, point-slope form is nothing too complicated.
You have all the information you need, and you can create your graph or write an equation in slope intercept form very easily. Write an equation in slope intercept form given the slope and y-intercept. In this case it denotes a specific y value which you will plug into the equation.
The slope intercept form calculator will help you find the equation of a line if you know two points it goes through.
While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler. Read on to learn what is the slope intercept form of a linear equation. Writing Linear Equations Given Slope and a Point When you are given a real world problem that must be solved, you could be given numerous aspects of the equation.
To write the equation, we need two things: We know the slope and a point x,y. Write down the coordinates of the first point. It will help you find the coefficients of slope and y-intercept, as well as the x-intercept, using the slope intercept formulas.
I substituted the value for the slope -2 for m and the value for the y-intercept 5 for b. We know how to use the point-slope form, so the final answer is: Locate another point that lies on the line. Now we know the slope m is 1.
Continue reading for a couple of examples! All you need to know is the slope rate and the y-intercept. Find the equation for this line in point slope form. Your final result should look like: The variables x and y should always remain variables when writing a linear equation.
This is the so-called slope intercept form, because it gives you two important informations: Y-intercept is the value of y at which the line crosses the y-axis. Notice that in the chart, the 2 grey sections slope and y-intercept are the two numbers that we need in order to write our equation.
Calculate the slope from the y-intercept to the second point. Point-slope form is also used to take a graph and find the equation of that particular line.You can find the straight-line equation using the point-slope form if they just give you a couple points: Find the equation of the line that passes through the points (–2, 4) and (1, 2).
I've already answered this one, but let's look at the process. Writing Linear Equations Given Slope and a Point. When you are given a real world problem that must be solved, you could be given numerous aspects of the equation.
If you are given slope and the y-intercept, then you have it made. You have all the information you need, and you can create your graph or write an equation in slope. While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler.
Point-slope form is also used to take a graph and find the equation of that particular line. How Do You Write an Equation of a Line in Slope-Intercept Form If You Have Two Points?
Trying to write an equation in slope-intercept form? Have two points on your line? You'll need to find your slope and y-intercept.
Watch this tutorial and see what needs to be done to write an equation in slope-intercept form! Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.
This can be done by calculating the slope between two known points of the line using the slope formula. Writing linear equations using the slope-intercept form. You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line).
It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis.Download
