Question 150369: If you can help me figure the points to plot, I can plot the points without any problem.
Plot the graphs of the following functions. Scan the graphs and post them to the Facilitator along with your response.
1. f(x)=7x
2. f(x)=4x - 3
3. f(x)=(1/5)x
4. f(x)= log3x

I'll do the first two to help you get started

# 1

Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is note: really looks like

Since this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

So we have one point

Now since the slope is comprised of the "rise" over the "run" this means

Also, because the slope is , this means:

which shows us that the rise is 7 and the run is 1. This means that to go from point to point, we can go up 7 and over 1

So starting at , go up 7 units

and to the right 1 unit to get to the next point

Now draw a line through these points to graph

So this is the graph of through the points and

Also, because the slope is , this means:

which shows us that the rise is 4 and the run is 1. This means that to go from point to point, we can go up 4 and over 1

So starting at , go up 4 units

and to the right 1 unit to get to the next point

Now draw a line through these points to graph

So this is the graph of through the points and
