graph{y>4x+2 [-10, 10, -5, 5]}

Explanation:

First, graph the line. The line is in y=mx+by=mx+b form and mxmx is the Slope and bb is the y-intercept. Since the slope is 44, the lines goes up by 44 for every x-value. Since the y-intercept is 22, it can be written as (0,2)(0,2), which is the point that the line touches when the x-value is 00.

However, we are graphing an inequality so we need to change the line to a dotted or solid one and shade either the top or the bottom. The inequality that you provided claims that yy is greater than 4x+24x+2. Since it's greater than, the top will be shaded. It doesn't say greater than or equal to so the line will be dotted. I hope this helps.
