How do you find the slope and y intercept for 5x+4y=12?
So let start by writing the equation again.
5x + 4y = 12
Now, to find the slope, you should start by subtracting 5x from both sides as you would want it in slope intercept form y = mx+b. Subtracting from 5x from both sides give us:
4y = -5x + 12
Now, we cannot have a number in front of y because that is breaking the rule of standard form for slope intercept form. So to make it slope intercept form, divide everything by 4y and you get this:
Now, I can further simply
So the slope of 5x + 4y = 12 is
