The scatter plot shows:

• positive association

• negative association

• no association

Given the ordered pairs, make a scatter plot of the data. If the data suggest a linear relationship, draw a trend line and write its equation.

(2, 5), (4, 8), (6, 12), (8, 14), (10, 18)

Given the ordered pairs, make a scatter plot of the data. If the data suggest a linear relationship, draw a trend line and write its equation.

Solve for the variable. 6(5n-4)+2n-8=64. n=
