We can't solve it with that information
The answer is 3 because you multiply 5 and 1 which is 5 and you subtract 2 from the 5 which leaves you with 3.
2 meters because 8/4 is 2
The simplified version would be 8nx - 7p - 6x
The slope is -4.7 because this equation is written in point slope form. This equation can be rewritten as y = -4.7x + 21. Point slope form is y = mx + b, with m being slope and b being y-intercept.
