Answer:
Vladimir and Robyn both are correct.
Step-by-step explanation:
Let us check whether the points (-5,-3) and (10,9) are on the line
or not.
The equation of the straight line passing through the given points (-5,-3) ans (10,9) is 
⇒ 5(y - 9) = 4(x - 10)
⇒ 5y = 4x + 5
⇒
.............. (1)
So, Vladimir is correct.
Now, Robyn says that the line passes through the points (-10,-7) and (-15,-11).
Then, both of the points satisfy the equation (1).
Therefore, Vladimir and Robyn both are correct. (Answer)
Answer:
3x-8y+40z
Step-by-step explanation:
You could use so many for example 4, 10, 57, 5729, any number above 4 would work since that plus 8 would be greater than 11
