The slope of y= 1/2x-7 is always positive because since the slope of this equation is “1/2”, 1/2 is always positive.
You could distribute this expression to get and even MORE simplified expression. Add the two terms in the parentheses together so that you get 4(7x). Now you can simply multiply 4 by 7x which would equal 28x. The new expression is 28x.
