Write the equation of the line that passes throught the point (-4,-9) and has a slope of 1/2
Ray Of Light [21]

Answer: y = 1/2x - 7

<u>Data</u>

Point = (-4, -9)

slope = m = 1/2

<u>Process</u>

To solve this problem, use the formula slope- y-coordinate, substitute the values and simplify.

<u>Equation</u>

 y - y1 = m (x - x1)

       x1 = -4

       y1 = -9

<u>Substitution</u>

y + 9 = 1/2 (x + 4)

<u>Simplification</u>

 y + 9 = 1/2x + 4/2

  y = 1/2x + 2 - 9

<u>Answer</u>

y = 1/2x - 7

\bf \textit{simmetry identities}\\\\&#10;sin(-\theta)=-sin(\theta)\\\\&#10;-------------------------------\\\\&#10;sin(-\theta)=\cfrac{1}{5}\implies -sin(\theta)=\cfrac{1}{5}\implies sin(\theta)=\cfrac{-1}{5}\cfrac{\leftarrow opposite=b}{\leftarrow hypotenuse=c}&#10;\\\\\\&#10;c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\implies \pm\sqrt{5^2-(-1)^2}=a&#10;\\\\\\&#10;\pm\sqrt{24}=a\implies \pm2\sqrt{6}=a

so. hmm which is it? the +/- ?   well, neverminding for a second, the value of tangent, just looking at the sign, the tangent is positive,

tangent = opposite/adjacent.... so that only happens, when both are the same sign, + or - both

now, we know the sine is -1/5.. if the sine is negative, the cosine also has t to be negative, so we'd use the -2√(6) = a

thus     \bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies cos(\theta)=\cfrac{-2\sqrt{6}}{5}
