Slope of -2 through point (5,2)
Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

Through -3 , -2 slope = -2/3​

y1 = -2 & x1 = -3 and m = -2/3

y - y1 = m(x - x1)

y - (-2) = -2/3(x - (-3))

y + 2 = -2/3(x + 3)

Multiply each term by 3

3y + 6 = -2(x + 3)

3y + 6 = -2x - 6

3y = -2x - 6 - 6

3y = -2x - 12

50 Points: Name the similar triangles &amp; Prove the similarity with details
Leno4ka [110]

<u>Let's consider the facts at hand</u>:

  • By Vertical Angle Theorem ⇒ ∠BCE = ∠DCF
  • ∠BEC = ∠DFC
  • Sides BE = DF

<u>Based on the diagram, triangles BCE and triangles DCF are similar</u>

   ⇒ based on the Angle-Angle theorem

      ⇒ since ∠BCE = ∠DCF and ∠BEC = ∠DFC

         ⇒ the two triangles are similar

Hope that helps!

<em>Definitions of Theorem I used:</em>

  • <u><em>Vertical Angle Theorem: </em></u><em>opposite angles of two intersecting lines must be equal</em>
  • <u><em>Angle-Angle Theorem:</em></u><em> if two angles of both triangles are equal, then the given triangles must be similar</em>

<em />
