Write a slope-intercept form of the equation if it passed the
inna [77]

Answer:

\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}

Step-by-step explanation:

We need to write the slope intercept form of the equation which passes through (4,-1) and parallel to the line y = -3/4x .

We know that the line parallel to a given line has the same slope . Therefore the slope of the line will be , ( on comparing to Slope Intercept Form ) .

\sf\longrightarrow Slope =\dfrac{-3}{4}

On using point slope form ,

\sf\longrightarrow  y-y_1= m ( x - x_1)

Substitute the respective values ,

\sf\longrightarrow y - (-1) = \dfrac{-3}{4}( x - 4 )

Simplify ,

\sf\longrightarrow y +1 = \dfrac{-3}{4}x + 3

Multiply both sides by 4 ,

\sf\longrightarrow 4y + 4 = -3x + 12

Put all terms on same side , i.e. on LHS ,

\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}

<u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> </u><u>the</u><u> line</u><u> </u><u>is </u><u>3x</u><u> </u><u>+</u><u> </u><u>4</u><u>y</u><u> </u><u>-</u><u> </u><u>8</u><u> </u><u>=</u><u> </u><u>0</u><u>. </u>

Sedbober [7]

Answer:

ACD = 120°

Step-by-step explanation:

Exterior angle theorem.

3x = (x + 12) + (x + 28)

3x = 2x + 40

 x = 40

ACD = 3x = 3(40) = 120°
