The equation y = 0.62x describes the approximate number of miles y in x kilometers. which of the following points is a solution of the equation y = 0.62x? a. (4.96, 5.58) c. (8, 4.96) b. (4.96, 8) d. (8, 8.62)

(8, 4.96)

Step-by-step explanation:

If a point (a,b) is the solution to the equation then its coordinates satisfy the above equation.

Check all points:

A. (4.96, 5.58)

False

B. (8, 4.96)

True

C. (4.96, 8)

False

D. (8,8.62)

False

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.
