Answer:
y = x + 4 (Answer A)
Step-by-step explanation:
Note that when x = 0, y = 4, so the y-intercept is (0, 4) Note also that as x increases by 1 from any given value to the next greater one, the 'run' is 1; the same behavior characterizes f(x). Thus, the slope of the line through the points indicated is m = 1/1 = 1.
Using the slope-intercept formula, y = mx + b, we get y = x + 4 (Answer A)
