What is the constant of proportionality in the graph below? (answer must be simplified fraction) PLEASE HELP I WILL MAKE U BRAINLIEST. IM LITERALLY GONNA FAIL IF I GET THIS WRONG. HELPPP

The constant of proportionality is

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities

To find the constant of proportionality from the given graph choose a point on the line and substitute x and y in the equation of the proportionality by the coordinates of the point.

∵ Point (4, 18) lies on the line

∴ x = 4, y = 18

∵ The equation is y = kx

→ Substitute x by 4 and y by 18

∴ 18 = k(4)

∴ 18 = 4k

→ Divide both sides by 4 to find k

∴

∴

→ Simplify the fraction by dividing up and down by 2

∴

∴ The constant of proportionality is

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

answer: 5100 just subtract
