Answer:
y = 15x
Step-by-step explanation:
The question asked, what equation shows the line through the data points. And it stated the equation needed to be in the form y = kx
Where
y represents the vertical axis
x represents the horizontal axis
k = constant
K is the constant interval and can be use to get the next points
y = kx
viewing the most visible points from the graph , let use the point where total saved is 90(y axis) and the time in weeks (x axis) is 6, the constant K can be gotten.
y = 90
x = 6
y = kx
90 = 6k
divide both sides by 6
k = 90/6
k = 15
Therefore,
y = 15x
