We substitute the given into the equation
given: a=-1, b=2, c=

=(

-1
=

-1
=

-1
=

-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:

=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=


×

(denominator should be -2=common)
=

+

=

which also = to -3.5

and so on, and then, you graph those x,y coordinates
Answer:
Solving the equation
we get 
Step-by-step explanation:
Noah's step to solve the equation
are:

The next step is to take square root on both sides because: 

Now, we know that: 

So, Solving the equation
we get 
Y=6x-27...........(1)
y=4x-17...........(2)
By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.
The answer is 6200
i think
