Answer:
t = 4d + 5
Step-by-step explanation:
Since the slopes in the answer choices are different, we can just find the slope.
Use the formula (y1-y2)/(x1-x2) to find slope. Take points (1,9) and (2,13) and plug them it to get (9-13)/1-2). Simplify to get (-4)/(-1), which simplifies to 4.
The only answer choice with 4 as a slope is D, t = 4d + 5
