Graph for 3*x
Steps to solve such questions :
Step 1: Put the equation in Slope Intercept Form i. e., y=mx+c
Here we have, Y = 3x +0 , where m =3
Step 2: Graph the y-intercept point (the number in the b position) on the y-axis. Here put x=0, we get Y =0. So, that point is ( 0,0).
Step 3: Find your second point with the help of given equation . Here, if we put x =1 then we have Y =3. So, the 2nd point is (1, 3). Plot it on the graph.
Step 4: Draw your line using the two points you plotted.
So, you will get your required graph.
