In this week of math I learned how to show different ways of slope and y-intercept equations. There are three different ways of showing the equation.
- slope intercept form
slope intercept form is one of the most basic and my personal favorite equation of the three. Y = mx + b
the M in this equation is = to slope
and B is the y-intercept
- point slope form
point slope form is like a harder version of slope intercept form. It’s not as bad as general form because when you look at a point slope form equation, it tells you what the slope
- general form
ax + by + c = 0
this is known as the “Useless” form. Because if you were to take a quick look at this equation, it would tell you nothing about it. Which means you get to do some very fun math.
2x – 3y – 3 = 0 first we have to decide on either we move the y to the other side of the equation or the 2x and -3. It would be easier to just move the y because the x is already positive on this side.
2x – 3 = 3y the y is now positive because it switched sides. Now we need to get rid of the lonely 3, we do that by adding 3 on each side.
2x = 6y now were on the last step, we now have to get y by itself. and to do that we will divide 6 on each side to finish it.
2/6x = y or 1/3x = y now your all done!
