What is the equation of a line perpendicular to y=2.5x+5

y = -0.4 + c

Step-by-step explanation:

y = mx + c (original form)

m ⊥ - 1/m

2.5 = 25/10

25/10 ⊥ -10/25

-10/25 = -0.4

y = -0.4x + c

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
