You can put this solution on YOUR website! Graph y=3x+1
Step 1. The equation is in slope-intercept form given as y=mx+b where m is the slope and b is the y-intercept when x=0 or at point (0,b).
Step 2. Comparing the given equation with y=mx+b shows that the slope m=3 and y-intercept is 1 when x=0 or at point (0,1).
Step 3. To graph, start with the point (0,1) and the slope means for every one unit to the right we go three units up since the slope is 3. This means that one point is (0+1,1+3) or (1,4) is a point on the line.
Step 4. Using the two points (0,1) and (1,4) we have the following graph of the line since it takes two points to make a line.
I hope the above steps and explanation were helpful.
