A line passes through (10,4) and (13,-11). Write the equation of the line in standard form.
AlexFokin [52]

\bf (\stackrel{x_1}{10}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{13}~,~\stackrel{y_2}{-11}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-11-4}{13-10}\implies \cfrac{-15}{3}\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=-5(x-10)


now

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

therefore,


\bf y-4=-5(x-10)\implies y-4=-5x+50\implies \blacktriangleright 5x+y=54 \blacktriangleleft

A circle with the diameter of 40 inches. what is the area?
Vsevolod [243]

Answer:

<em>A= 1256</em>

Step-by-step explanation:

<u>The formula for area of a circle is </u>A=\pi r^{2}

1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. <em>40/2 = 20. </em>

<em>2. </em>Then, plug in the values into the area formula. <em>A= 3.14</em>(20^{2})

3. Solve.<em> A= 1256</em>. (Remember that 20 squared is <em>20x20</em>)
