Linear Equations

In Linear Equations, there are two different types of linear equations. The two types of linear equations are the slope-intercept formula and the point-slope formula. Both ask for the same thing, but they are both formatted differently, but you get the same answer afterwards.

For the Slope-Intercept Formula, you use the equation, y=mx+b.

If the questions gives you a slope and a point on the line:
If there a question that gives you a point and the slope, then you fill in those three number you get under y, m and x. With that, you only need to find b, and then after you finish the equation by putting back m, and the new value of b that you retrieved.

If the questions give you only two points:
If there is a question that gives you only two points, you have to use the slope formula to find the slope between the two points. After that, you do the same what you do with a point and slope, fill them all for y, m and x, and find b.


Point Slope Formula is almost the same as the slope-intercept formula, but the formula for this is                 y-y1 = m(x-x). Unlike the slope-intercept, there is no need to find out what is b is, but to know what is y1, x and m is. Y and X is not required to be found in the slope-intercept formula. They also are the only two that should not be filled in with numbers. 

If the questions gives you a slope and a point on the line:
Just fill in the slope and the two points given in y1, x and m. 

If the questions give you only two points:
Find the slope of the two points, and then use one of the points (it doesn't matter, because any point you pick will be the same) and put them under y1, x and m
