# Write an equation in point slope form for the line through the given points calculator

This means that the x-axis will represent the time passed and the y-axis will represent the distance to the car.

Real world uses of y-intercept and x-intercept We have already seen what is the slope intercept form, but to understand why the slope intercept form equation is so useful you should know some applications it has in the real world.

If we take values closer and closer to 0 something like 0. And we just have to remind ourselves that slope, slope, is equal to, slope is equal to change in y over change in x.

Negative four times X is negative four X. So let's do that. The way it works is by using derivatives, linear equations, and x-intercepts: This method consists of choosing a value of x for the equation and calculating the derivative of the equation at that point.

So now that we have a, now that we know the slope and we know a point, we know a, we actually know two points on the line, we can express this in point-slope form.

Let's distribute this negative four. So this is going to be equal to the slope 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. Equations with no intercept asymptote We can distinguish 3 groups of equations depending on whether they have a y-intercept only, an x-intercept only or neither.
