10. Mrs. Hamilton surveyed some of her students by asking how many minutes they spent studying for their math test and the score they made on the math test. The results are shown
below.
a. What is the slope of the trend line?
100
b. What does the slope mean in the context of the
situation?
90

e. Write the equation of the trend line:

asdasd

step-by-step explanation:

answer: 590

step-by-step explanation:

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

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.
