What is the length of a diagonal of a cube with a side length of 3 cm? 18 cm
127 cm
33 cm
38 cm

so mark-up is 0.4 multiplied by 180 = 72

your answer is b.

step-by-step explanation:

the 2 points are: (3,1) and (6,6)

first, let's find the slope:

(6-1)/(6-3) = 5/3

then let's plug this into the point-slope formula:

y - 1 = 5/3(x - 3)

this is your answer! the below is just the simplified form.

y - 1 = 5/3x - 5

y = 5/3x - 4
