Yesterday Mica was given some information and was asked to find a linear equation. But last night her cat destroyed most of the information! At right is all she has left:

Complete the table and graph the line that represents Mica’s rule.

Because the equation is linear, the growth must be constant.

Use the points below to graph the line represented by Mica's chart

Mica thinks the equation for this graph could be

. Is she correct? Explain why or why not. If not, find your own algebraic rule to match the graph and table.Put the equation into

form and see if the growth rate and-intercept match the line you graphed in part (a).
