What is an equation for a graph that is parallel to the graph of y equals -0.5x plus 2?
y = -0.5x plus or minus any number
Which point lies on the line described by the equation y minus 8 equals 3x plus 3?
(2, 11)
What are the values of x and y which satisfy the equations x plus 2y equals 27 and 2x minus y equals 19?
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
What is the solution for y equals -x and 2x-y equals 6?
-4
How do you rewrite this equation so that y is a function of x 2x plus y equals 7?
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
If x squared minus y squared equals 10 and x plus y equals 5 what is x minus y?
2
Is y equals x minus 2 a nonlinear equation?
No, y=x-2 is linear.
What is the gradient in y equals three and two thirds x minus four?
Well, darling, the gradient in y = 3⅔x - 4 is simply 3⅔. That's the number in front of the x, in case you missed it. So, if you were planning on plotting this bad boy on a graph, just remember that's the steepness of your line.
What is the answer to x over 4 minus y over three equals one?
x=4, y=3
What is the Sum of three x minus y equals twelve?
What is 3x-6y=12
Solve using substitution x minus y equals 2 and x plus y equals -4?
-2
How do you solve -x plus y equals 1 and -2 plus y equals -2 by substitution?
-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
What is the y-intercept of the equation 2x minus 5y equals -10?
-2
What is the solution of the equation y equals 2x plus 10?
the answer is y minus 10 divided by 2.
What is the slope of y minus 2x equals negative 3?
The slope is 2 and the y intercept is -3
The line given by the equation y equals 5x minus 2 is perpendicular to what equation?
It is: y = -1/5x-2
2x plus 5y equals 2 and -3x minus y equals -3?
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
