What method can be used to write the equation of a line in slope-intercept form given two points? pl answer im being timed

slope intercept form is : y = mx + b

where m is the slope and b is the y-intercept.

The slope, m = (y' - y)/(x' - x)

Is found using the two pints.

The apostrophe is used to denote the other point, different from point (x,y).

once you have the slope, m for the equation y = mx + b ; use one of the points as (x,y) to solve for b.

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.
