Sagot :

Answer:

  y = 1/3x +3

Step-by-step explanation:

Here, it will be convenient to write the equation in "slope-intercept form." That looks like ...

  y = mx +b . . . . . line with slope m and y-intercept b

__

The y-intercept is the y-value where the line crosses the y-axis. On your graph, there is a point there: (0, 3). That means the y-intercept is b=3.

The slope is the "rise" divided by the "run". The points on your graph are 3 units apart horizontally (run = 3). The point on the right is 1 unit above the point to its left (rise = 1). This means the slope of the line is ...

  m = rise/run = 1/3

Now, you have what you need to write the equation:

  y = 1/3x +3
