Converting from slope-intercept to standard form.
We can use that to figure out how long it will take him to save all the money he needs to buy the MP3 player. In this kind of equation, x and y are variables and A, B, and C are integers.
Well, we said X equals zero, this disappears. To change this into standard form, we start by moving the x-term to the left side of the equation.
Worksheet on standard form equation pdf with answer key on this page's topic. It is effective in describing some of the characteristics of a straight line. Andre wants to buy an MP3 player.
C 8, 5 Incorrect. So we know the line passes through the point 1, 80. Finally, we must get rid of the fraction so, we clear the fraction by multiplying by the common denominator of all of the terms which is 4.
And it's slope would be M. But you still have to think about is it negative? So divide everthing by 16. Standard Form. Equation 1 and equation 4 are the only ones in standard form. I've just graphed, I've just graphed, this is the line that represents all the X and Y pairs that satisfy the equation 9X plus 16Y is equal to 72.
So if nine times X is 72, 72 divided by nine is eight.
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. And we wanted to graph this. This is pretty straightforward since the line is already in standard form.
