We know how to use the point-slope form, so the final answer is: We know the slope and a point x,y. It went from 2 to 5, so it changed by 3 it went up 3. Therefore the slope of this line is 2.
It went from 3 to 1, so it changed by -2 it went down 2. You could have used any triangle to figure out the slope and you would still get the same answer. As you can see, point-slope form is nothing too complicated.
You have it in point-slope form, which is what the question asked you to do. You must always know the slope m and the y-intercept b. You have all the information you need, and you can create your graph or write an equation in slope intercept form very easily.
And of course, if you need more help, feel free to ask the volunteers on our math help message board. Pick either 2,3 or 5,1. Find the equation for this line in point slope form. Write a linear equation that can be used to determine the cost of a cab ride to anywhere around Washington DC.
The standard point slope formula looks like this: If you are given slope and the y-intercept, then you have it made. You have enough information to find the y-intercept, but it requires a few more steps. Do the arithmetic, and this will give you the value of b. It could be slope and the y-intercept, but it could also be slope and one point or it could be just two points.
Then the slope is:Point-slope form is all about having a single point and a direction (slope) and converting that between an algebraic equation and a graph.
In the example above, we took a given point and slope and made an equation. 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. What is (2,-4),m=5 in point slope form How to turn point-slope linear equation into standard form What is point slope form Write the point-slope form of the line that passes through (6, 1) and is parallel to a line with a slope of One type of linear equation is the point slope form, which gives the slope of a line and the coordinates of a point on it.
The point slope form of a linear equation is written as. In this equation, m is the slope and (x 1, y 1) are the coordinates of a point.
Finding the Equation of a Line Given Two Points – Notes Page 3 of 4 Example 3: Find the equation of the line passing through the points (–5, –2) and (1, 5). Step 1: Find the slope of the line. To find the slope of the line passing. Algebra > Lines > Finding the Equation of a Line Given a Point and a Slope.
