i need help with graphing (f)x = 3x+2
thank you
This is just a line with slope = 3 and y-intercept = 2
To draw a line, all we need are two points, the intercepts are always good points to use.
For x-intercept, set
So our x-intercept is
For y-intercept, we simply have the lone constant as the intercept. So our y-intercept is at , which is the point
But why is this? Let's see.
For y-intercept, set
So the y-intercept is
Now just plot these points on a graph and draw a straight line through them, as you see below
