Answer:
(B) y = x - 8
Explanation:
The slope is found by looking at the change in y divided by the change in x.
The line goes through grid intersections that differ both horizontally and vertically by 1 unit, so ...
m = rise/run = 1/1 = 1
The y-intercept is where the line crosses the y-axis, at y = -8. The slope-intercept equation is then ...
y = mx + b . . . . m = slope (1); b = y-intercept (-8)
y = x - 8 . . . . matches choice B
