Answer:

y = -5x + 6

Step-by-step explanation:

To find the slope of a line you have to use the following formula:

y2 - y1 / x2 - x1

choose any 2 rows for "x" and "y" (it doesn't matter), but "x" and "y" have to come from the same row. (I'll do the third and fourth rows)

x1 = 1

y1 = 1

x2 = 2

y2 = -4

(-4 - 1) / (2 - 1)

-5 / 1

slope (m) = -5

the equation of a line is y = mx + b

m = slope

b = y-intercept

pick any row to plug "x" and "y" into the equation so you can find "b" (I'll choose row three); you already know the slope (m)

1 = -5(1) + b

1 = -5 + b

b = 1 + 5

b = 6

plug everything in to the equation y = mx + b

equation: y = -5x + 6

12. In the given figure, RS is parallel to PQ, If RS = 3 cm, PQ = 6 cm and ar(∆TRS) = 15cm³, then ar (∆TPQ) = ? (a) 70 cm² (b) 5
Gnesinka [82]

\large\underline{\sf{Solution-}}

Given that,

In <u>triangle TPQ, </u>

  • RS || PQ,

  • RS = 3 cm,

  • PQ = 6 cm,

  • ar(∆ TRS) = 15 sq. cm

As it is given that, <u>RS || PQ</u>

So, it means

⇛∠TRS = ∠TPQ [ Corresponding angles ]

⇛ ∠TSR = ∠TPQ [ Corresponding angles ]

\rm\implies \: \triangle TPQ \:  \sim \: \triangle TRS \:  \:  \:  \:  \:  \:  \{AA \}

<u>Now, We know </u>

Area Ratio Theorem,

This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.

\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{ar( \triangle \: TRS)}  = \dfrac{ {PQ}^{2} }{ {RS}^{2} }

\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15}  = \dfrac{ {6}^{2} }{ {3}^{2} }

\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15}  = \dfrac{36 }{9}

\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15}  = 4

\rm\implies \:ar( \triangle \: TPQ)  = 60 \:  {cm}^{2}
