What do you mean? Question not clear.
Xy = k
4x = 7
Divide both sides by 4
x = 7/4
Answer:
<h2>y = -35x + 105</h2>
Step-by-step explanation:
The given graph represents a function between hours and miles.
To determine the equation that belong to this graph, first we need to find the slope using two points from the graph: (0, 105) and (3, 0).
The definition of slope is
Notice that the slope is -35. Remember that the slope is always the coefficient of variable . So, the choice that has this slope is the right answer.
Therefore, the right answer is the last choice: y = -35x + 105
