Question 726077: How do you convert y= -x +-12 from slope intercept form to standard

You can put this solution on YOUR website!
slope intercept form is y = mx + b
m is the slope
b is the y intercept

standard form is ax + by = c
a is the coefficient of x
b is the coefficient of y
c is the constant.

to convert from slope intercept form to standard form, you need to get both the x and the y on the left side of the equation.

assuming your equation is y = -x - 12, you would do the following:

add x to both sides of the equation to get:
x + y = -12

in this equation, that's all you have to do.
you are in the form of:
ax + by = c
a is equal to 1
b is equal to 1
c is equal to -12
