Determine the slope (9,2) and (3,-8)

Oxana [17]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 9 &,& 2~) 
% (c,d)
&&(~ 3 &,& -8~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-8-2}{3-9}\implies \cfrac{-10}{-6}\implies \cfrac{5}{3}$

5. y = 2x + 6<br> 2x - y=2

Crank

Step-by-step explanation:

$y = 2x + 6$

$2x - y = 2$

To solve this system of equations, let's first add the equations together:

$(y) + (2x - y) = (2x + 6) + (2)$

$2x = 2x + 8$

$2x - 2x = 8$

$0 = 8$

There are no values of $x$ that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.
