The first thing we must do in this case is to define the variables.
We have then:
v: the value of the bicycle
t: years
The standard equation of the line is:
v-vo = m (t-to)
The slope is:
m = (v2-v1) / (t2-t1)
Substituting values:
m = (640-850) / (3-0)
m = -70
We choose an ordered pair:
(to, vo) = (0, 850)
Substituting values:
v-850 = -70 (t-0)
Rewriting:
v = -70t + 850
Answer:
assuming it decreases in value by the same amount each year, a linear equation for the value of the bicycle, v, when it is t years old is:
v = -70t + 850
When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.
Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.
See the drawing attached below.
Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:
m<DIE + m<HID = 18
40 + m<HID = 180
m<HID = 140
Similarly:
m<BHC + m<CHI = 180
130 + m<CHI = 180
m<CHI = 50
Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:
m<DIE = m<GIH = 40
m<GIE = m<HID = 140
m<CHI = m<AHB = 50
m<BHC = m<AHI = 130
