You can put this solution on YOUR website! How to sketch this graph f(x)=3x+2 and g(x)=-5x+2
=======================
they're straight lines, so you need 2 points.
f(x)=3x+2
Pick 2 values for x and find f(x)
---
x = 0 --- f(x) = 2 ---> the point (0,2)
x = 3 --- f(x) = 11 --> the point (3,11)
Plot the 2 points, draw a line thru them.

You can put this solution on YOUR website! Both functions are in slope-intercept form.
f has intercept (0,2) and is of slope 3.
Use that to sketch or draw the line.
g has intercept (0,2) and is o slope -5.
Use that to sketch of draw the line.
