Explain what the slope and intercept mean in each situation. 1a. A graph represents the total number of miles walked, y, after 2 weeks. The slope of the line is 3 and the y-intercept is 0.

Then why is the question on here if you know the answer

The answer would be a

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
