Find the equation of the line specified. The slope is 7, and it passes through (3,-1).
a. y = 7x - 22
b. y = 7x + 20
c. y = 7x-1
d. y = 14x - 22

If n stands for number sold and c stands for cost per item, in which column would you use the formula: ? a. column d c. column f b. column e d. column g

What is the rate of change of a line that passes through (2,-5) and (6,-2)?
