Which expression gives the area of the triangle shown below?
kvasek [131]
The answer is d. The reason this is the answer is because to find the area of a triangle you will find half of the base times the height. The formula looks like this: A=1/2bh.

On this picture the base is the length of the bottom part of the triangle (c). It is the distance of the solid line only.

The height is represented as the straight line that is perpendicular to the base (forms a right/90 degree angle). X is the height of the triangle.

Therefore, 1/2cx is the answer.

A line passes through the point(-4,-6) and has a slope of 1/2 What is the<br> equation of the line?
alex41 [277]

Answer:

x-2y-8=0

Step-by-step explanation:

The equation of line is given by the relation

y-y1=m(x-x1)

where m is the slope

now, given x1=-4 and y1=-6 and the slope is 1/2.

<em>sub</em><em>stitute</em><em> </em><em>in</em><em>to</em><em> the</em><em> equation</em><em> </em><em>to</em><em> </em><em>get</em>

<em>y</em><em>+</em><em>6</em><em>=</em><em>1</em><em>/</em><em>2</em><em>(</em><em>x</em><em>+</em><em>4</em><em>)</em>

<em>mult</em><em>iplying</em><em> </em><em>through</em><em> </em><em>wi</em><em>th</em><em> </em><em>the</em><em> </em><em>L.C.M</em>

<em>whi</em><em>ch</em><em> </em><em>is</em><em> </em><em>2</em>

<em>2</em><em>(</em><em>y</em><em>+</em><em>6</em><em>)</em><em>=</em><em>1</em><em>/</em><em>2</em><em>×</em><em>2</em><em>(</em><em>x</em><em>+</em><em>4</em><em>)</em>

<em>2</em><em>y</em><em>+</em><em>1</em><em>2</em><em>=</em><em>x</em><em>+</em><em>4</em>

<em>maki</em><em>ng</em><em> </em><em>x</em><em> </em><em>the</em><em> </em><em>su</em><em>bject</em>

<em>x</em><em>=</em><em> </em><em>2</em><em>y</em><em>+</em><em>8</em><em> </em><em>hence</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>li</em><em>ne</em><em> </em><em>is</em><em> </em><em>x-2y-8</em><em> </em><em>=</em><em>0</em>
