Simple..

you have y which is the cost of the tickets..and you have x which is the number of tickets..

So, you have those points on the graph....find an equation!

Take any of those coordinates..and find the equation of the line...in the form of y=mx+b

(2,10) and (5,25)

Using: $\frac{ y_{1}- y_{2} }{ x_{1}- x_{2} }$

$\frac{10-25}{2-5} = \frac{-15}{-3} =5$

Thus, you know your slope. m=5

But, remember it's in the form of y=mx+b

So, use any of the coordinates...let's use (2,10)

10=5(2)+b

10=10+b

0=b

Thus, your equation is... y=5x

Thus, your answer.

Are the two triangles below similar? Triangles GHI and JKL are shown. Angle G equals 46 degrees, Angle I equals 27 degrees, Angl

Scilla [17]

Answer: No; they do not have proportional corresponding sides

Step-by-step explanation:

Since, here in triangles GHI and JKL,

∠ G = 46°, ∠I = 27° ⇒ ∠H = 107° , ∠L = 27°, ∠ K = 108°⇒∠J = 45°

GH = 4, HI = 5 , KJ= 2 and JL = 4

Here ∠I ≅ ∠L

But, $\frac{GH}{JK} \neq \frac{HI}{JL}$
