Answer: y - 10.6 = 9(x-1)
Step-by-step explanation:
x travels from -5 to 5
y stays constant at 8
Quotient is given by y/x
Hence our answer is .

Here h can't be 0 as it makes the diction undefined.

Option B
Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
You have to divide the numerator (the top number) by the denominator (the bottom number). For example: 1/2 is a fraction, its equivalent (equal) decimal is .5. How did we get that? Divide the 1 by the 2 :) I hope this helps :)
