The next problem, we have been given a graph.
00:05
Now, first of all, we need to identify the type of model, which is we need to determine whether it is linear or exponential.
00:13
Now, from the graph, we can see that the plotted points form a straight line.
00:19
They seem to lie on a straight line.
00:21
And since they seem to lie on a straight line, hence the model is a linear model.
00:29
Next, we need to construct the appropriate model using information and values from the graph.
00:37
So since it's a linear model, the model will be the equation of a straight line.
00:44
Now if we know two points, x1, y1 and x2 y2 that a straight line passes through, then the equation of that line will be y minus y1 equals to y2 minus y1 by x2 minus x1 times x minus x1.
01:07
So in this case from the graph we can see that the graph passes through the point 0 ,000.
01:16
So we can consider x1 to be 0 and y 1 to be 1 ,000.
01:21
And the topmost point is 8117.
01:28
The hint is that the score was 1170 in week 8.
01:31
So that means the point is 8 and 1170.
01:37
So we can just substitute these values.
01:39
So y minus y 1...
