Answer:

Step-by-step explanation:

y - y_{1} = m( x - x_{1} ) point - slope form of linear equation ;

y = mx + b slope-intercept form of linear equation, (0, b) are coordinates of y-intercept ;

<em>(b).</em> y - 3 = - 7(x - 8)

<u><em>y = - 7x + 59</em></u>

<em>(c).</em> y - (- 2) = \frac{4}{3} [ x - ( - 7)] ⇔ y + 2 = \frac{4}{3} ( x + 7)

<u><em>y = </em></u>\frac{4}{3}<u><em> x + </em></u>\frac{22}{3}<u><em> </em></u>

<em>(d).</em> <u><em>y = - </em></u>\frac{7}{8}<u><em> x + 9</em></u>

Triss [41]

Answer:

<em>In </em><em>the </em><em>above</em><em> </em><em>figure</em>

<em>both </em><em>the </em><em>sides </em><em>are </em><em>equal</em><em> </em><em>then</em><em> </em><em>angle </em><em>between</em><em> </em><em>them </em><em>will </em><em>also </em><em>equal</em>

<em>so,</em>

<em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>3</em><em>x</em><em>+</em><em>1</em><em>)</em><em> </em><em>=</em><em> </em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>7</em><em>5</em><em> </em>

<em>x </em><em>=</em><em> </em><em> </em><em>1</em><em>7</em><em>5</em><em>/</em><em>7</em>

<em>x </em><em>=</em><em> </em><em>2</em><em>5</em>

hence angle will (25 *2) +2 =52

other angle is( 25*3)+1 = 76

<em>hope </em><em>it </em><em>helps</em><em> </em><em>and </em><em>your </em><em>day </em><em>will </em><em>fine</em>
