The table below shows that Y changes in relation to X at a constant rate. x Y

Eric graphed the information in the table and connected the points of the graph with a line.
Which feature of Eric's line represents the unit rate of change of Y in relation to X?

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

b

step-by-step explanation:

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.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2
