The generic equation of the line is:
y-yo = m (x-xo)
The slope is:
m = (y2-y1) / (x2-x1)
m = (- 2-0) / (3-0)
m = -2 / 3
We choose an ordered pair
(xo, yo) = (0, 0)
Substituting values:
y-0 = (- 2/3) (x-0)
Rewriting:
y = (- 2/3) x
Answer:
The equation of the line is:
y = (- 2/3) x
She expects to receive about $5.00 because the total cost of the items is $12.13 so if you subtract how much money she brought and how much money she spent, ($17-$12.13) it would equal $4.87 which would round up to $5.00
The answer would be the first one because the angle measurement of a straight line is 180°
