Answer:

y = 4/3x +2

Explanation:

The graph crosses the y-axis at y=2, so that is the y-intercept.

The points have a rise of 4 units for each horizontal run of 3 units, so the slope is ...

m = rise/run = 4/3

The slope-intercept equation for the line is ...

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

y = 4/3x +2
