Write an equation in slope intercept form with two given points calculator

How to find the equation of a line with one point

So let's do that. They say that the line goes through the point negative 4 comma negative And to get this in this form we just have to simplify a little bit of this algebra. Change in Y over change in X. We know that the slope between any two points on this line is going to be negative four. Let me write it in green. A b that makes this equation, or that satisfies the constraint that when x is equal to negative 4, y is equal to negative Actually, I forgot to label the x-axis right over there. The first group y-intercept only can have almost any type of equation, including linear equations. On the left-hand side we're just left with Y. So we're on the y-axis. We have the same linear equation, but it's now represented in slope-intercept form.

In real life, arriving at the exact minimal point is not possible to do in a finite amount of time, so typically people will settle for a "close enough" value. And our slope is equal to rise over run.

So we'll move down seven, so the line will look roughly like this. Once again, we see the slope right over here and now we can figure out what the y-intercept is. So the equation of our line is y is equal to 7x, that's our slope. The y-intercept when X is equal to zero, Y is going to be equal to So that tells us that when x is equal to negative 4, then y is equal to negative And so this green line represents all of the solutions to this linear equation. When x is 0, y is So y is negative 11 when x is equal to negative 4. And now we know b is Slope intercept formula derivation Still need to know how to find the slope intercept form of a linear equation? Let me write it in green. So hopefully, we're a little familiar with the slope already.

In this article, we will mostly talk about straight lines, but the intercept points can be calculated for any kind of curve if it does cross an axis. So that's slope right over here. It is the value of x at which the straight line crosses the x-axis it means the value of x for which y equals 0.

Slope intercept form calculator with steps

The y-intercept just tells us where we intercept the y-axis. So your change in, let me write this. If you move one in the x direction, you have to move up seven. They tell us we go through the-- Let me just, in a new color. And now we know b is We could say b is equal to 8. The more we go down in this situation, for every step we move to the right, the more downward sloping will be, the more of a negative slope we'll have. Well, anything times 0 is 0.

What is the slope intercept form? If you move one in the x direction, you have to move up seven.

This is the so-called slope intercept form, because it gives you two important pieces of information: the slope m and the y-intercept b of the line. Then the value of x at this point will be the time when you and the car were at the same place. In general, any time that a function has an asymptote that lies on one of the axis, it will be missing at least one of the intercepting points. So let's see, we get negative 11 is equal to 7 times negative 4 is negative 28 plus b, and now we can add a 28 to both sides of this equation. Linear equations, or straight line equations, can be quickly recognized as they have no terms with exponents in them. This will be the point 0 comma b. So negative 11 is equal to 7 times x-- and in this case x is negative plus b. Other equations with y-intercept The car example above is a very simple one that should help you understand why the slope intercept form is important and more specifically, the meaning of the intercepts.

That's not green. The y-intercept is Obviously, haven't done it very exactly, but our line is going to look like. What is the equation of this line in slope-intercept form?

It's movement can be plotted as time versus the distance the car is from you as shown above.
