Step-by-step explanation:
the slope is the ratio y/x (or here distance/time) indicating how many units y changes, when x changes a certain amount of units when going from one point to another.
so, we have 2 points here
(0.2, 3)
(0.4, 6)
x (or time) changes by 0.2 units (from 0.2 to 0.4).
y (or distance) changes by 3 units (from 3 to 6).
therefore, the slope is 3/0.2 = 3/(1/5) = 3/1 / 1/5 = 3×5/1×1 = 15
that means based on the graph, that the object travels 15 miles in 1 minute.
3 times 1 is 3. Take 3 minus 7 equals -4.
The answer is (1 , -4)
-k/7 = -4
k/7 = 4
k = 7 × 4
k = 28
