Hiker's Elevation 3,000-
Hiking The scatter plot shows a hiker's elevation
above sea level during a hike from the base to the
top of a mountain. The equation of a trend line for
the hiker's elevation is y = 9.23x +686, where x
represents the number of minutes and y represents
the hiker's elevation in feet. Use the equation of the
trend line to estimate the hiker's elevation after 140
minutes.

idk man good luck man

Answer from: Quest

option a is correct.

$\frac{\text{original height}}{\text{original base}}=\frac{\text{reduction height}}{\text{reduction base}}$

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

$\frac{\text{original height}}{\text{original base}}=\frac{\text{reduction height}}{\text{reduction base}}$

Which is the scale factor proportion for the reduction shown? answers are on picture.
