Which of the following is the algebraic expression that best describes the height y, if x is the width?

it's a graph with the points
(0.5, 1.5)
(2, 6)
(3, 9)
(5, 15)

the answer choices are
a. y=x+3
b. y=3x

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

if im undersanding the question correctly, its organized from 10
