How do you change #3x+y=15# into slope intercept form?

Answer 1

Eva Adamson

Form of a slope-intercept is:

#y = mx + n#

Simply subtract #3x# from each side of the equation and:

#y = -3x + 15#

To change the equation 3x + y = 15 into slope-intercept form, you need to isolate y on one side of the equation. To do this, first subtract 3x from both sides of the equation:

3x + y - 3x = 15 - 3x

This simplifies to:

y = -3x + 15

Now, the equation is in slope-intercept form, y = mx + b, where m is the slope (-3 in this case) and b is the y-intercept (15 in this case).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
