What is a linear graph?
A linear graph represents a straight-line relationship between two variables, showing constant rate of change and proportional behavior.
1) No, Nora does not deposit $1 into the account every 8 week.
2) No, the account does not start with $8 in it. Rather it starts with $4, this corresponds to the y-intercept of the graph. That is the point where the line intersect the vertical axis.
At this point, the number of week is zero.
3) Yes, Nora deposits $8 into the account every week.
From the graph
At week 1
Total amount = 12
At week 2
Total amount = 20
At week 3
Total amount = 28
This is read from the intersection between the week number and the line graph traced to the vertical.
