Question

weather data
the equation for the line of best fit is ( y = -x + 84 ). according to the equation, which of these statements is true?
a city with a latitude of ( 0^{circ}n ) could expect to have a january high temperature of about ( 84^{circ}f ).
a city with a latitude of ( 40^{circ}n ) could expect to have a january high temperature of about ( 55^{circ}f ).

Explanation:

Step1: Substitute \(x = 0\) into the equation \(y=-x + 84\)

When \(x = 0\), \(y=-0+84=84\)

Step2: Substitute \(x = 40\) into the equation \(y=-x + 84\)

When \(x = 40\), \(y=-40 + 84=44
eq55\)

Answer:

A. A city with a latitude of \(0^{\circ}N\) could expect to have a January high temperature of about \(84^{\circ}F\).
