A linear function f(x) contains the coordinates (-9, 4) and (6,4). Joy says f(x) is a horizontal line, and Lu says f(x) is a vertical line. Which student correctly described the function? Explain. A. Joy because (-9,4) and (6,4) would have a slope of zero which is a horizontal line.

B. Joy because (-9,4) and (6,4) would have a slope of zero which is a vertical line.

C. Lu because (-9,4) and (6,4) would have a slope of zero which is a horizontal line.

D. Lu because (-9,4) and (6,4) would have a slope of zero which is a vertical line.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
