What is the slope of the line through point (2/3, 4/7) and (2/3, 11/7)

mart [117]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ \frac{2}{3} &,& \frac{4}{7}~) 
% (c,d)
&&(~ \frac{2}{3} &,& \frac{11}{7}~)
\end{array}
\\\\\\
% slope = m
slope \implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{\frac{11}{7}-\frac{4}{7}}{\frac{2}{3}-\frac{2}{3}}\implies \cfrac{\frac{7}{7}}{0}\implies \cfrac{1}{0}\impliedby un de fined$

$-2$

The graph of the equation is attached in the figure below

Step-by-step explanation:

We need to make the graph of the equation: $|x|+1$

Solving the equation:

$|x|+1$

Applying absolute rule: |u|<a, a>0 then -a<u<a

So,

$-2$

The graph of the equation is attached in the figure below.

Solve the system of equations by substitution - 5x+8y= -86 <br>y=6x-43

n200080 [17]

Answer:

(6 ,-7)

Step-by-step explanation:

$- 5x + 8y = - 86 \\ y = 6x - 43 \\ - 5x = - 86 - 8y \\ x = 17.2 + 1.6y \\ y = 6(17.2 + 1.6y) - 43 \\ y = 103.2 + 9.6y - 43 \\ 8.6y = - 60.2 \\ y = - 7 \\$
