Question 52186
To graph the line, I first come up with the equation.


The standard equation of a line is {{{y = mx + b}}}, where m = slope, and b = y-intercept (i.e. where the line crosses when x = 0).


In your case, m = 2, and y = 3.  So, the equation is {{{y = 2x + 3}}}


Then, all you need to do is figure out two points on the line and connect them together.  


You already know one: (0, 3)  (when x = 0, y = 3)
Pick any value of x, and calculate its corresponding y value.  I'll pick x = 1.  Then, I have the point (1, 5)


Then graph:


{{{graph(300,300,-5,5,-3,10,2x+3)}}}
