How do you graph #y=1/4x-4# by plotting points?
You need only two points to plot your function, that represents a straight line.
This is a linear function that will give you, when plotted, a straight line.
First you can see that the slope of your line is positive
Also, the line crosses the y-axis at
So basically when
To plot a line you need only 2 points, so, the next could be chosen at
So, you can now plot your line through points of coordinates:
