Write the equation in general form of a line with a slope of 1 and y intercept of -1

x-y=1
x-y-1=0
-x+y+1=0
-x+y=-1

x - y = 1

Step-by-step explanation:

To begin, substitute m=1 and b=-1 into the slope intercept form y=mx+b.

y=x-1

Convert to the standard form by subtracting x to the other side.

-x + y = -1

In standard form, the coefficient of x cannot be negative. Multiply the entire equation by -1.

-1(-x + y = -1)

x - y = 1
