How would you graph y = 2x + 3 and its inverse?

1) To graph y = 2x +3, give  2 different value for x & find its related y value:

for instance if x = 0 , then y = 3

                   if x =  1,  then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.

2) The inverse of y=2x+3

a) Switch the x & y ===> x=2y+3

b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y

c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y

And the inverse function of y = 2x+3 is y= 1/2(x+3)
