when the equation can be written in the form y=mx+b
the graph is a straight line that is not vertical

when you can write any equation for it

x= 149. 24+7=31. 180-31=149

it would be 3 ÷by 6 because the number on each side

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

c(x)= 6x + 3
