You switch the x and y coordinates of the line. In other words, (x,y) ---> (y,x). I hope this helps! :)
substitute x = y and y = -x Ex: y = x2 becomes -x = y2
The whole line 'shifts up' by two units, and is parallel to the original line (same slope)
(2, -2)
that is an equation of a line with a slope of 1 and y-intercept of -3 and x-intercept of 3
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
The diagonal line collapses into a single point on that line.
Infinitely many: they are the same line!
y equals x plus 5 is the equation of a straight line in the x-y plane.
You switch the x and y coordinates of the line. In other words, (x,y) ---> (y,x). I hope this helps! :)
Y is undefined because the line x=1 never crosses the y axis.
y=x y=1x The slope is one.
y=-x+4
No, they are perpendicular.
Slope of a line perpendicular to x-y=16
Any line with a slope of 1 is parallel to y=x-3.
A line that followed y = 0 would be exactly the same as the line of the x axis.
