To write equation of a line in two-point form, simply substitute the coordinates of the given two points in the equation ( y − y 2 ) = y 2 − y 1 x 2 − x 1 ( x − x 2 ) . Example: Find the equation of a line passing through the points and . Substitute the values in ( y − y 2 ) = y 2 − y 1 x 2 − x 1 ( x − x 2 ) .
In general form they would be the same. So you can use whichever you prefer. So I'm going to say yMoreIn general form they would be the same. So you can use whichever you prefer. So I'm going to say y minus 6. Equals now my slope is up here negative eight over three times x minus X1 was 1..
So I use a point. And I'll use that point to give me. 10. Which confirms that b equals negative 7.MoreSo I use a point. And I'll use that point to give me. 10. Which confirms that b equals negative 7. So now when I finally want to write this equation.
To write numbers in standard form, we follow a simple process. First, we identify the number between 1 and 10 and then determine how many times we need to multiply it by 10 to get the original number. Let's take the number 5,000 as an example. We can write it in standard form as 5 x 10^3.
If given two points, first find the slope (m) of the line that contains the points. Then write an equation in slope-intercept form (y=mx+b) and substitute in the x and y values for one of the points to find the y-intercept (b). Then convert to standard form (Ax+By=C) by subtracting the (mx) term from each side.
So let's find the slope. And that would be 7 minus 3 and that would be negative one minus two. SoMoreSo let's find the slope. And that would be 7 minus 3 and that would be negative one minus two. So our slope is four over negative three so it's negative four thirds. Now we need to um pick a point.

It. Positive over 6 which equals uh divide you'll have a -4/3. So now we know m. Equal a -4/3. SoMoreIt. Positive over 6 which equals uh divide you'll have a -4/3. So now we know m. Equal a -4/3. So when writing my equation using my point slope form I'm going to now put -4/3 in for M.

How to Find the Equation of a Line from Two Points Find the slope using the slope formula. Use the slope and one of the points to solve for the y-intercept (b). Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
