Point-slope form is also used to take a graph and find the equation of that particular line. And of course, if you need more help, feel free to ask the volunteers on our math help message board.
Think about it this way: Your slope was given to you, so where you see m, use 2. You must always know the slope m and the y-intercept b. Once you have m slope and b y-interceptyou can write an equation in slope intercept form. Then we can write our equation. In this case it denotes a specific y value which you will plug into the equation.
We know how to use the point-slope form, so the final answer is: We also now know the y-intercept bwhich is 3 because we just solved for b. You have all the information you need, and you can create your graph or write an equation in slope intercept form very easily. Write a linear equation that can be used to determine the cost of a cab ride to anywhere around Washington DC.
Find the equation for this line in point slope form. Try working it out on your own. While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler.
Just plug the given values into your point-slope formula above. We also now know the y-intercept bwhich is 9 because we just solved for b. Note also that it is useful to pick a point on the axis, because one of the values will be zero.
As you can see, point-slope form is nothing too complicated.
You have a starting point on a map, and you are given a direction to head. Your final result should look like: The slope is going to be your "rate" and the point will be two numbers that are related in some way.Algebra > Lines > Finding the Equation of a Line Given a Point and a Slope.
Page 1 of 2. Let's find the equation of the line that passes through the point (4, -3) Finding the Equation of a Line Given Two Points. Parallel Lines. Perpendicular Lines. Writing Algebra Equations Finding the Equation of a Line Given Two Points.
We have written the equation of a line in slope intercept form and standard form. We have also written the equation of a line when given slope and a point.
Now we are going to take it one step further and write the equation of a line when we are only given two points that.
Find the Equation of a Line Given That You Know Two Points it Passes Through The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.
Write the equation of a line, in slope intercept form, that passes through the point (6, -3) with a slope of Let's first see what information is given to us in the problem. We'll record this information in the chart below to keep it organized. Find the Equation of a Line Given That You Know a Point on the Line And Its Slope The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
If you a point that a line passes through, and its slope, this page will show you how to find the equation of the 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.Download
