The standard for of this equation is x – y = 0
Firstly, options A and D are not in standard form, so they are not options.
To decided between B and C, we choose a point on the line and see if it works. For example, we'll use (2, 2).
x – y = 0
2 - 2 = 0
0 = 0
This is true for option C. Therefore, it is correct.
Answer:
we cant answer if we dont know what sin A is
804 miles/12 hours = 67 miles
Which means that Ivan drove 67 miles per hour
67 miles*9 hours = 603 miles
Which means that in 9 hours Ivan can drive 603 miles if he drives at a constant speed of 67 miles per hour.
