Answer:
B) d=4t
Step-by-step explanation:
let's look at two points
1. t=0, d = 0
2. t = 1, d = 4
slope = change in vertical axis (d)/ change in horizontal axis (t)
change in d = 4 = d₂-d₁
change in t = 1 = t₂-t₁
slope = 4/1 = 4
vertical variable = slope * horizontal variable + horizontal axis intercept
d = 4 * t + horizontal axis intercept
horizontal axis intercept is the vertical axis variable (d) when the horizontal axis variable (t) is at 0. at t=0, d=0
thus, d = 4 * t + 0
d = 4t (B)
