Best ResponseYou've already chosen the best response.0Identify the initial value and rate of change for the graph shown (4 points) Initial value: 1, rate of change Initial value: , rate of change: 0 Initial value: 1, rate of change Initial value: , rate of change: 0

Best ResponseYou've already chosen the best response.1A lot of the info is missing from your choices. The initial value is definitely 1.

Best ResponseYou've already chosen the best response.1Where the line crosses the yaxis is a good point. What are the coordinates of that point?

Best ResponseYou've already chosen the best response.1It is the point where the line crosses the yaxis. From the origin (the point where the xand yaxes intersect), how far right or left do you go to that point?

Best ResponseYou've already chosen the best response.1That means the xcoordinate is 0. Point A has an xcoordinate of 0. We already have: (0, ) Now we need the ycoordinate of point A.

Best ResponseYou've already chosen the best response.1Right, so the coordinates of point A are: (0, 1)

Best ResponseYou've already chosen the best response.1Now we need to look at the original graph and find another easy point to read.

Best ResponseYou've already chosen the best response.1An easy point to read lies on the intersection of grid lines. Start at point A, start going up to the right along the line, and tell me what is the first point along the line that is on a grid intersection?

Best ResponseYou've already chosen the best response.1Look at my figure above. Going up to the right on the line, which is the first point on the line that is on a grid intersection? Copy my drawing and put a mark on the point you think it is.

Best ResponseYou've already chosen the best response.1Use the drawing just above here. I forgot one grid line in the earlier drawing.

Best ResponseYou've already chosen the best response.1Look below. Would you agree that the line passes right by a grid intersection there? dw:1436815638584:dw

Best ResponseYou've already chosen the best response.1Let's call the new point B. The coordinates of point B are (5, 4) dw:1436815721902:dw

Best ResponseYou've already chosen the best response.1Now we need the slope between points A and B.

Best ResponseYou've already chosen the best response.1Point A(0, 1) Point B(5, 4) Slope = (difference in ycoordinates)/(difference in xcoordinates) Slope = (4  1)(5  0) = 3/5 The rate of change is 3/5, and the initial value is 1.

Best ResponseYou've already chosen the best response.0Bentley had $40 in birthday money in her piggy bank. She spent $10 on new flipflops, then got $20 for her allowance and did not spend any of that money for 1 week. Finally, she spent $15 on new sunglasses. Which part of the scenario is best represented by a linear increasing interval?
