Answer:

Part a) The unit rate of change of d with respect to t is equal to 9

Part b) The graph of the line corresponding to the attached diagram

Step-by-step explanation:

we know that

The relationship between the variables t and d depicts a proportional change if described in the form d/t=k or d=kt

step 1

Determine the value of k

we have

t=0.2, d=1.8

k=d/t

substitute

k=\frac{1.8}{0.2}=9

so

the resulting linear equation equals

d=9t

step 2

utilize a graph tool

plot the line d=9t

La opción correcta es D. tarjeta 4. Explicación paso a paso: Observa el gráfico proporcionado. El APR introductorio es una tasa de interés reducida que las compañías de tarjetas de crédito suelen ofrecer a nuevos clientes durante un número determinado de meses. La mayoría de las tarjetas de crédito brindan APRs descontados en pagos, transferencias de saldo o en ambos. El gráfico de la tarjeta 4 muestra que la tasa de interés entre enero y abril fue menor, y después de abril, la tasa de interés aumentó con una pendiente diferente. Por lo tanto, la opción correcta es D. tarjeta 4.
