Find the equation for a line with the equation y=xy=x.

STEP 1

Assumptions
1. We are given the equation of a line in the form y=xy = x.
2. We need to express this equation in the standard form of a linear equation, which is Ax+By=CAx + By = C, where AA, BB, and CC are constants.

STEP 2

The given equation is already in a form that represents a line. The slope-intercept form of a line is y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

STEP 3

In the given equation y=xy = x, the slope mm is 1 (since xx is the same as 1x1x) and the y-intercept bb is 0 (since there is no constant added to xx).

STEP 4

To write the equation in standard form Ax+By=CAx + By = C, we can simply rewrite the given equation by moving xx to the left side of the equation.

STEP 5

Subtract xx from both sides of the equation to move it to the left side.
yx=0y - x = 0

STEP 6

Now, the equation yx=0y - x = 0 is in the standard form Ax+By=CAx + By = C, where A=1A = -1, B=1B = 1, and C=0C = 0.
The equation for the line is x+y=0-x + y = 0.
