Since the equation has degree 2 there must be exactly 2 roots

x²-4x+4=0
(x-2)²=0
x =2

2 is a root of multiplicity 2

Step-by-step explanation:

-4x + 9y = -22

-9x -9y = 126

-13x = 104

x = -8

8 +`y = 14

y = 6

Answer:

$\huge\boxed{\sf The\ co-efficient\ of\ x\ is\ -4.}$

Step-by-step explanation:

Slope = m = -4

Y-intercept = c = -7 ( Because that is the point where x = 0 )

<u>Equation:</u>

$\sf y = mx+c\\\\y = -4 x+(-7)\\\\y = -4x-7$

So, The co-efficient of x is -4.

$\rule[225]{225}{2}$
