The coordinates of the x intercept for the equation y equals x plus 1 is (x=-1, y=0).
If the equation is: y = -x then the slope is -1 and there is no y intercept
x=3 y=3.5
It is a linear equation in the variables x and y.
y equals x plus 5 is the equation of a straight line in the x-y plane.
x = 2 and y = -4
x = 0 and y = 4
The 'x' and 'y' intercepts of that equation are both at the origin.
The coordinates of the x intercept for the equation y equals x plus 1 is (x=-1, y=0).
If y = y + x then x must be 0 Otherwise the equation is meaningless.
If the equation is: y = -x then the slope is -1 and there is no y intercept
X = 11.5
x=3 y=3.5
It is a linear equation in the variables x and y.
y = -5
y equals x plus 5 is the equation of a straight line in the x-y plane.
It could be y = -x+5
