The given equation is expressed as
y = - x
We would substitute values for x into the equation to get corresponding values for y. Thus, we have
If x = 0, y = 0
If x = 1, y = - 1
If x = 2, y = - 2
If x = 3, y = - 3
We would plot these values on the graph as shown below
The values of x are plotted on the horizontal axis while the values of y are plotted on the vertical axis.
The x intercept is the value of x when y = 0
If y = 0, then
0 = - x
x = 0
Thus, x intercept = 0
The y intercept is the value of when x = 0
If x = 0, then
y = - 0
y = 0
Thus, y intercept = 0
