Answer:
The Answer : 19/8 Not sure if I'm correct
The answers is A x=4.5y because for whatever y is you multiply it by 4.5 and it gives you your x. Trust me. They all match too; I checked.
For this case we have, by definition:

So, we have:

On the other hand we have that by definition:

Thus, the expression can be written as:




So, we have:

Answer:

Answer:
y = 5x - 21
Step-by-step explanation:
Since we already know the slope, all we need to do is plug the values of x and y into the equation.
y = 5x + b
-1 = 5(4) + b
-1 = 20 + b
-21 = b
The equation is y = 5x - 21.
