I have two questions on two math problems.

You cannot "solve" them; You can graph them.

1. f(x)=x+5
Let x = 0, Then y = 5 giving you point (0,5)
Let x = 2, then y = 7 giving you point (2,7)
Plot those points and draw a line thru them to get:

---------------------------------------------
2. f(4)=8x+2
Let x = 0, then y = 2 giving you point (0,2)
Let x = 2, then y = 18 giving you point (2,18)
Plot the points and draw a line thru them to get:
