Question

How do you graph the equation `y=3x+1`?

Answer 1

Start at (0,1) and go up 3 and over 1 to (1,4) connect the points.

Explanation:

`y= 3x + 1` is in the slope intercept form

`y = mx + b`

m = the slope in this case 3
b = the y intercept in this case 1.

Think of b the y intercept as the beginning this is where to start the graph.

So start with (0,1) the y intercept and make the first point at (0,1)

Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line

So in this case go up three on the y axis and over 1 on the x axis.
make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)

Now connect the points. creating the line
