Answer:
t = √(2d/a)
Step-by-step explanation:
To solve for a variable, undo the operations done to that variable, in reverse order. Here, t is squared, then multiplied by a/2.
d = (a/2)t^2
Multiply by 2/a.
2d/a = t^2
Take the square root.
Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.
