The line Y=2 is a horizontal line at positive 2..
So the Y intercept is 2.
Think of a normal line equation.
Y=mX+b
B is the y intercept, and since there is no "mx" term, m, which is the slope, equals 0, which means it's a horizontal line.
x2 / y = (6)2 /2 = 36/2 = 18
There is no slope nor intercept because there is no equation, simply an expression.
y equals 2

It shows the relationship of y in terms of x. [y = (yIntercept) + ((slope)*(x))] [slope = (y2 - y1)/(x2 - x1)]
x2 / y = (6)2 /2 = 36/2 = 18
There is no slope nor intercept because there is no equation, simply an expression.
x/y = 5/(y^2) and y/x = 5/(x^2). So x/y + y/x = 5/(y^2) + 5/(x^2), which equals 5x^2/(x^2 y^2) + 5y^2/(x^2 y^2) equals 5(x^2 + y^2)/25 equals (x^2 + y^2)/5. x^2 = 25/y^2, so you get (25/y^2 + y^4/y^2)/5 equals ((25 + y^4)/y^2)/25, which shows that your math teacher is on crack. Seriously, I'm not sure that's true.

y equals 2
Y/2
Half correct because x = 2 and y = 6
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.

-1
A pair of simultaneous eq;ns. 3x + y = 4 x + y = 0 Subtract the two eq'ns. This will eliminate 'y' 2x = 4 x = 2 Substitute this value of 'x' into either eq'n for 'y' 2 + y = 0 y = -2 or 3)2) + y = 4 6 + y = 4 y = 4 - 6 y = -2 ( again) . So the answer is ( x,y) = ( 2, -2).
