what is the slope of x+y=5
x + y = 5y = -x + 5y = -1*x + 5The slope of the line is the coefficient of the x term when the equation is written in y = mx + b form.So, the slope of x + y = 5 is -1.
I think my answer will help you:Step 1: x+y=5Step 2 : I translate x in the other side like this y= -x + 5
