y = -0.5x plus or minus any number
(2, 11)
x + 2y = 27 2x - y = 19 y = 2x - 19 x + 2(2x - 19) = 27 x + 4x - 38 = 27 5x = 65 x = 13 y = 2(13) - 19 y = 7
-4
y=f(x)= x(2x+y)=7 f(x)=2x^2 +xy -7 = 0 y=2x^2 +xy -7 y-xy -7 + 2x^2 = 0 y(1-x)=2x^2-7 y=(2x^2-7) / (1-x) Excuse the working. Y equals 2 X squared minus 7 all divided by 1-X
2
No, y=x-2 is linear.
three and two thirds
x=4, y=3
What is 3x-6y=12
-2
-x+y = 1 -2+y = -2 y = 1+x y = -2+2 => y = 0 By sustituting the values of x and y can be found x = -1 and y = 0 Remember that a minus from a minus is equal to a plus. So - -1+0 = 1
-2
the answer is y minus 10 divided by 2.
The slope is 2 and the y intercept is -3
It is: y = -1/5x-2
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
