so we have a table of values, with x,y coordinates, so let's use any two of those points to get the slope of the table and use the point-slope form to get its equation

$~\hspace{2.7em}\stackrel{\textit{let's use}}{\downarrow }\qquad \stackrel{\textit{and this}}{\downarrow }\\\begin{array}{|lr|r|r|r|r|}\cline{1-6}x&0&1&2&3&4\\y&-1&3&7&11&15\\\cline{1-6}\end{array}\\\\[-0.35em]\rule{34em}{0.25pt}\\\\(\stackrel{x_1}{1}~,~\stackrel{y_1}{3})\qquad(\stackrel{x_2}{4}~,~\stackrel{y_2}{15})$

$\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{15}-\stackrel{y1}{3}}}{\underset{run}{\underset{x_2}{4}-\underset{x_1}{1}}}\implies \cfrac{12}{3}\implies 4\\\\\\% point-slope intercept\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{4}(x-\stackrel{x_1}{1})\\\\\\y-3=4x-4\implies y = 4x-1\implies \blacktriangleright y = 4x+(-1)\blacktriangleleft$

A student is using the completing the square method to transform the equation x2-10x+ 36 = 0 to the form (x-h) 2+k = 0. which st

andreev551 [17]

Obviously the Correct Step would give him the correct answer lol !

But, here he goes !!

$( {x}^{2} - 10x + 36)$

$= ( {x}^{2} - 2(x)(5) + {(5)}^{2} ) + 11$

$= (x - 5)^{2} + 11$

✓ So, h = 5 ; k = 11 would make him correct

When solving a system of equations, how do you determine which method to use?

lisov135 [29]

How can you determine the best method of solving a system of equations?

Elimination is best used when both equations are in standard form (Ax + By = C).

Elimination is also the best method to use if all of the variables have a coefficient other than 1.

Hope this helps
