The cost, c(x), for a taxi ride is given by c(x) = 2x+4.00, where x is the number of minutes. what does the slope mean for this equation. a, the rate of change of the cost the taxi ride is 4.00$ per minute (b. the rate of the change of the cost of the taxi ride is 2.00$ per minute (c. the taxi ride costs 2.00$ per trip. (d. the taxi ride costs a total of 4.00$

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
