Answer:

DIBF

Explanation:

It is helpful to look at the value of the y-intercept and the sign of the slope. The y-intercept is the y-value where the line crosses the y-axis. The slope is the "rise" divided by the "run". You can count horizontal and vertical grid squares between the y-intercept and the next grid crossing to determine the slope.

The slope-intercept equation is ...

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

__

1.

y-intercept is -3, slope is negative (-1/3). Matches choice D.

2.

y-intercept is 0. Matches choice I.

3.

y-intercept is 1, slope is negative and is steep (-3). Matches choice B.

4.

y-intercept is 3, slope is negative (-1/2). Matches choice F.

The code is DIBF.
