Please help. Just in case the picture isn't showing A proportional relationship is graphed on a coordinate plane. The point (4, 10) is on the graphed line. Lynn said, " If x = 4 and y = 10, then the constant of proportionality is 6 ". Lynn's claim is not true If x = 4 and y = 10, what is the constant of proportionality?

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
