Barry owns a music store, he recorded the sales of a newly launched album as part of his biweekly inventory. the table shows the number of weeks, x, since the launch of the album and the number of albums sold during that time period, f(x).

x 0 2 4 6 8

f(x) 0 78 152 222 288

use the data in the table to create the standard form of the function that models this situation.

f( = x2 + x +

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
