Answer: 5.60
Step-by-step explanation: Divide 2.10 by 3. You get 0.7. Then multiply 0.7 by 8 and you get 5.60.
Well from positive y axis Q is situated at 6 units while P is situated at 3 units.
So length of PQ - 6+3 = 9 units.
Rounding up your answer is 10 units
The constant term should be +6

Answer: C) perpendicular</h3>
Explanation:
Each equation given to you is in y = mx+b form (aka slope intercept form).
The slope m is what we'll focus on.
The first equation has slope of 1, while the second equation has slope -1.
The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.
Or you could note that -1 is the negative reciprocal of 1, or vice versa.
So there are a few options to see why the lines are perpendicular.
