Answer:
The answer is 9x - y - 3 = 0
Step-by-step explanation:
The line passing through the point (x₁, y₁) and has a slope of m,
y – y₁ m(x – x₁)
where, (x₁, y₁) = (1, 6) and m = 9
y – 6 = (9)(x – 1)
y − 6 = 9x – 9
-9x + y – 6 + 9 = 0
-9x + y + 3 = 0
Divide both side by (-1) we get,
-9x + y + 3/(-1)= 0/(-1)
9x - y - 3 = 0
Thus, The answer is 9x - y - 3 = 0

Answer:
1st one and the third one
Step-by-step explanation:
25(0)=25
25+0=25
X² + 1 = 0
=> (x+1)² - 2x = 0
=> x+1 = √(2x)
or x - √(2x) + 1 = 0
Now take y=√x
So, the equation changes to
y² - y√2 + 1 = 0
By quadratic formula, we get:-
y = [√2 ± √(2–4)]/2
or √x = (√2 ± i√2)/2 or (1 ± i)/√2 [by cancelling the √2 in numerator and denominator and ‘i' is a imaginary number with value √(-1)]
or x = [(1 ± i)²]/2
So roots are [(1+i)²]/2 and [(1 - i)²]/2
Thus we got two roots but in complex plane. If you put this values in the formula for formation of quadratic equation, that is x²+(a+b)x - ab where a and b are roots of the equation, you will get the equation
x² + 1 = 0 back again
So it’s x=1 or x=-1
Green t-shirt=profit of $1
White t-shirt=profit of $3
Black t-shirt=profit of $1.
To find the answer, selling price minus total money spent (shirt, printing)
If the number is negative, it’s loss, and if it’s positive, it’s profit
