Hey! :)
So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!
-2x + y = 9
add 2x to both sides
y = 2x + 9
So C is your answer.
Please let me know if you need anything further explained!
Answer:
Rational
Step-by-step explanation: it equals 40, and 40 is rational
4x + 3y = 6 ⇒ -24x - 18y = -36
-6x - 2y = -24 ⇒ <u>-24x - 8y = -96</u>
<u>-10y</u> = <u>60</u>
-10 -10
y = -6
4x + 3(-6) = 6
4x - 18 = 6
<u> + 18 + 18</u>
<u>4x</u> = <u>24</u>
4 4
x = 6
The orderd pair (6, -6) is a solution of the system of equations.
