Topic: Transforming lines
1. Graph the following linear equations on the grid. The equation y = x has been graphed for you. For
each new equation explain what the number 3 does to the graph of y = x. Pay attention to the
y-intercept, the x-intercept, and the slope. Identify what changes in the graph and what stays the
same.
a.
y = x + 3
b. y = x-3
c. y = 3x
2. The graph of y = x is given. (See figure 2.) For each equation predict what you think the number-2
will do to the graph. Then graph the equation.
a. y = x + (-2)
Prediction:
b. y = x- (-2)
Prediction:
c. y = -2x
Prediction:
Please help!

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
