Do these two linear equations represent the same line? Why or why not? ................. y + 3 = 4(x - 2) and 2x + y + 13= 2 + 6x
Yes, because they both have the same slope-intercept form ... y = -11 + 4x

Write an equation that represents the number of mosquito's ................. There are 2000 mosquito's at your picnic! Luckily, your best friend brought a citronella candle, which pushes away half of the mosquito's every minute ................. Let t represent the number of minutes and m represent the number of mosquito's.
m = 2000(1/2)t

Make one table that is linear and one table that is exponential. Explain how you know that your tables are correct.
Tables will vary. First table is linear because the rate of change is constant by addition. Second table is exponential because the growth factor is constant by multiplication.

Write and solve a system of equations for the following situation ................... Rocky and Bullwinkle both collect fidget spinners. Together they have 11 total! Rocky bought his for $5 each and Bullwinkle bought his for $8 each, for a total of $67 spent. ................... How many fidget spinners do they each have?
r + b = 11 and 5r + 8b = 67 ................... r = 7 and b = 4 ................... Rocky has 7 fidget spinners and Bullwinkle has 4 fidget spinners.
