Yesterday Mica was given some information and was asked to find a linear equation. But last night her cat destroyed most of the information! Below is all she has left: 439 HW eTool (Desmos). Homework Help ✎
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 y = mx + b form and see if the growth rate and yintercept match the line you graphed in part (a).
