Graph the function f(x) = 2X+3

Step-by-step explanation:

From the given function, f(x) = 2X+3, whose graph is a straight line, we know that the slope is 2 and the y-intercept (b) is 3, or better (0, 3).

Plot a dark dot at (0, 3) (the y-intercept).  Now, with your pencil point on this dot, move 1 unit to the right (to (1,  3)), and from there move your pencil point 2 units up (because the slope is 2).  Plot another dark dot there, at (1, 5).

Now draw a straight line through these two points.
