Sagot :
Algebraic:
Swap x and y and then solve for y to get the inverse
y = -x+b
x = -y+b
x+y = b
y = -x+b
Therefore, the equation y = -x+b is its own inverse.
-------------------------
Graph:
Plot y = -x+b on the xy grid. Select whatever value you want for b. Let's say we go for b = 7. So we have y = -x+7 to plot. This line goes through (7,0) and (0,7) as the x and y intercepts respectively.
If we mirror this line over y = x, then points on y = -x+7 will end up somewhere else on this same exact line. The lines y = x and y = -x+7 are perpendicular. They intersect at a 90 degree angle.
This verifies that y = -x+7 is its own inverse, and by extension the same applies to y = -x+b where b is any real number.
See the image screenshot below. I used Desmos to graph it. GeoGebra is another useful tool I use all the time.
