Answer:
-4/5
Step-by-step explanation:
Lets put the equation in slope intercept form
4x+5y = -20
Subtract 4x from each side
4x-4x+5y = -4x-20
5y = -4x-20
Divide each side by 5
5y/5 = -4x/5 -20/5
y = -4/5 x -4
The equation is in the form y = mx+b where m is the slope and b is the y intercept
the slope is -4/5 and the y intercept is -4
<span>Well if you look at the two methods you can clearly see that you add downwards for synthetic and you subtract downwards for long division. Long division is also known as Remainder theorem, this is when you divide and subtract the terms to get a remainder, if the remainders is 0 then the divisor is a factor. Synthetic is merely just another technique for solving cubics and higher order polynomials</span>
This is a linear function.
If you were to plot these numbers on a graph, they would form a straight line.
