Answer:
y = 3x -2
Step-by-step explanation:
The graph shows a straight line that crosses the y-axis at y=-2. It has a "rise" of 3 grid squares for each 1 grid square to the right, so it has a slope of 3/1 = 3.
In slope-intercept form the equation is ...
y = mx + b . . . . where m is the slope, and b is the y-intercept
y = 3x -2
_____
In functional form, the equation might be written ...
A(x) = 3x -2 . . . . . Function A
