The value of a building bought in 1990 appreciates, or increases, as time passes. 5 years after the building was bought, it was worth $138 comma 000; 17 years after it was bought, it was worth $162 comma 000.
a. If this relationship between number of years past 1990 and value of building is linear, write an equation describing this relationship. [Use ordered pairs of the form (years past 1990, value of building). Let x represent the number of years since 1990 and y represent the value of the building.]

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

x coordinate is none
