How to write an equation in standard form using 2 points

So standard form for a quadratic equation is ax squared plus bx plus c is equal to zero. So essentially you wanna get all of the terms on the left-hand side, and then we want to write them so that we have the x terms

Standard form linear equations Video transcript - [Voiceover] We've already looked at several ways of writing linear equations. You could write it in slope-intercept form, where it would be of the form of Y is equal to MX plus B, where M and B are constants.

M is the coefficient on this MX term right over here and M would represent the slope. And then from B you're able to figure out the y-intercept. The Y, you're able to figure out the y-intercept from this. Literally the graph that represents the XY pairs that satisfy this equation, it would intersect the y-axis at the point X equals zero, Y is equal to B.

And it's slope would be M. We've already seen that multiple times. We've also seen that you can also express things in point-slope form. So let me make it clear. And these are just different ways of writing the same equations.

You can algebraically manipulate from one to the other.

Enter any Number into this free calculator $ \text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 } $ How it works: Just type numbers into the boxes below and the calculator will automatically calculate the equation of line in standard, point slope and slope intercept forms. The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations. Linear equations can be written in many forms. Discover how to use two coordinate points to solve for a line's slope and write an equation in slope-intercept form.

Another way is point-slope. And in point-slope form, if you know that some, if you know that there's an equation where the line that represents the solutions of that equation has a slope M. Slope is equal to M. This is point-slope form and we do videos on that. But what I really want to get into in this video is another form.

And it's a form that you might have already seen. And that is standard form.

And what I want to do in this video, like we've done in the ones on point-slope and slope-intercept is get an appreciation for what is standard form good at and what is standard form less good at?

So let's give a tangible example here.

Summary: Forms of two-variable linear equations

So let's say I have the linear equation, it's in standard form, 9X plus 16Y is equal to And we wanted to graph this. So the thing that standard form is really good for is figuring out, not just the y-intercept, y-intercept is pretty good if you're using slope-intercept form, but we can find out the y-intercept pretty clearly from standard form and the x-intercept.

The x-intercept isn't so easy to figure out from these other forms right over here. So how do we do that? Well to figure out the x and y-intercepts, let's just set up a little table here, X comma Y, and so the x-intercept is going to happen when Y is equal to zero.

And the y-intercept is going to happen when X is equal to zero.

So when Y is zero, what is X? So when Y is zero, 16 times zero is zero, that term disappears, and you're left with 9X is equal to So if nine times X is 72, 72 divided by nine is eight.

So X would be equal to eight. So once again, that was pretty easy to figure out.We NEVER store your card info. We NEVER charge anything unless you requested it.
