9x+y=11
That is interesting but not particularly useful. Do you have another line to go with it so we can see where the cross?
9x + y = 11
Solve for y
9x - 9x + y = -9x + 11
y = -9x + 11
Solve for x
9x + y - y = -y + 11
9x = -y + 11
9x/9 = -y/9 + 11/9
x = -y/9 + 11/9
The given equation is 9x + y = 11.
To solve for the values of x and y that satisfy this equation, we can use algebraic methods. Let's start by rearranging the equation to solve for y in terms of x.
9x + y = 11
Subtract 9x from both sides:
y = 11 - 9x
Now that we have y in terms of x, we can choose any value for x and determine the corresponding value of y. This will give us a set of solutions for the equation.
For example, let's choose x = 1. Plugging this value into the equation, we find:
y = 11 - 9(1)
y = 11 - 9
y = 2
So, when x = 1, y = 2 is a valid solution for the equation.
Similarly, we can choose any other value for x and calculate the corresponding value of y.
This equation represents a straight line in a coordinate system, where x and y are the Cartesian coordinates. Each solution (x, y) corresponds to a point on this line. By substituting different values for x, we can find multiple points on the line and sketch it if required.
