Rebecca was curious whether △ S T V △STVtriangle, S, T, V and △ W U V △WUVtriangle, W, U, V are similar. She wrote a proof and came to the conclusion that they are not similar, but her proof is wrong.

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

sry but any answer choices

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
