Although you have the slope, you need the y-intercept. Write a linear equation that can be used to determine the cost of a cab ride to anywhere around Washington DC.

Create the equation that describes this line in point-slope form. Now we know the slope m is 1. Example 2 Find the equation in point-slope form for the line shown in this graph: The slope is going to be your "rate" and the point will be two numbers that are related in some way.

You could have used any triangle to figure out the slope and you would still get the same answer. If you are given slope and the y-intercept, then you have it made. Then you will solve for b. Once you have m slope and b y-interceptyou can write an equation in slope intercept form.

Point-Slope Calculator Many functions to try! Your slope was given to you, so where you see m, use 2. We can use this information to solve for b.

As you can see, point-slope form is nothing too complicated. Putting it all together, our point is -1,0 and our slope is 2. Using the Point-Slope Form of a Line Another way to express the equation of a straight line Point-slope refers to a method for graphing a linear equation on an x-y axis.

You must always know the slope m and the y-intercept b. We also now know the y-intercept bwhich is 9 because we just solved for b. Now you are ready to solve real world problems given two points. Your point is -1,5. Finding the slope requires a little calculation, but it is also pretty easy.

The standard point slope formula looks like this: This relation means that we know the x and y coordinates of an ordered pair. You have a starting point on a map, and you are given a direction to head. Note also that it is useful to pick a point on the axis, because one of the values will be zero.

Think about it this way: Find the equation for this line in point slope form. Now we know the slope m is -2 because that was given to us.

Writing Equations Given Slope and a Point Write the equation of a line, in slope intercept form, that passes through the point 6, -3 with a slope of Point-slope form is also used to take a graph and find the equation of that particular line.

In this case it denotes a specific y value which you will plug into the 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.In the example above, we took a given point and slope and made an equation.

Now let's take an equation and find out the point and slope so we can graph it. Example 2. Find the equation (in point-slope form) for the line shown in this graph: Solution: To write the equation, we need two things: a point, and a slope.

Write an equation in slope-intercept form of the line that passes through the given point and has the given slope m. Then, rewrite in standard form. (-6,3), m = 2/3.

It's called the point-slope formula (Duh!) You are going to use this a LOT! Luckily, it's pretty easy -- let's just do one: Let's find the equation of the line that passes through the point. 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. Start studying Writing Linear Equations in Slope-Intercept Form.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Write the equation of the line with the given slope and y-intercept. Write the equation of the line that passes through the point with the given slope.
