my ixl learning assessment analyticses - 8th grade > find the rule: word problems yshglazed donut shop has a special deal going on. the more cups of coffee a customer buys, the more free donut holes they get. the table below shows the number of donut holes the customer gets, d, based on the number of cups of coffee they buy, c.input (c) output (d)1 42 53 64 7write an equation that describes the relationship between c and d.d = □submitwork it outnot feeling ready yet? these can help:input/output tables: find the rule (83)compare patterns

Explanation:

Step1: Identify slope (rate of change)

Slope $m = \frac{d_2-d_1}{c_2-c_1} = \frac{5-4}{2-1} = 1$

Step2: Find y-intercept (constant term)

Use $c=1, d=4$: $4 = 1(1) + b \implies b=3$

Step3: Write linear equation

$d = mc + b$

Answer:

$d = c + 3$
