<h2>Therefore Tahlia made mistake. Tahlia did not write -6 in her equation.</h2>

Step-by-step explanation:

Given , line n passes through the points (-3,-7.5) and (2,-5)

$x_1 = -3 , y_1=-7.5$ and $x_2 = 2 , y_2=-5$

Therefore the slope of the line is (m) $=\frac{y_1-y_2}{x_2-x_1}$

$=\frac{-7.5+5}{2+3}$

$=\frac{2.5}{5}$ $=\frac{1}{2}$

Therefore the equation of line is

$y-y_1=m(x-x_1)$

$\Leftrightarrow y+7.5 =\frac{1}{2}(x+3)$

$\Leftrightarrow y+7.5 = 0.5x+1.5$

$\Leftrightarrow y = 0.5x+1.5 -7.5$

$\Leftrightarrow y = 0.5x -6$

Therefore Tahlia made mistake. Tahlia did not write -6 in her equation.

What is the solution of the system? Use elimination.

sweet [91]

Answer:

The solutions to the system of the equations by the elimination method will be:

$x=2,\:z=-1,\:y=2$

Step-by-step explanation:

Given the system of the equations

$2x\:+\:2y\:+z\:=\:7$

$-x-\:y\:+z\:=\:-5$

$x+3y-4z=12$

solving the system of the equations by the elimination method

$\begin{bmatrix}2x+2y+z=7\\ -x-y+z=-5\\ x+3y-4z=12\end{bmatrix}$

$\mathrm{Multiply\:}-x-y+z=-5\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-2x-2y+2z=-10$

$\begin{bmatrix}2x+2y+z=7\\ -2x-2y+2z=-10\\ x+3y-4z=12\end{bmatrix}$

$-2x-2y+2z=-10$

$+$

$\underline{2x+2y+z=7}$

$3z=-3$

$\begin{bmatrix}2x+2y+z=7\\ 3z=-3\\ x+3y-4z=12\end{bmatrix}$

$2x+6y-8z=24$

$-$

$\underline{2x+2y+z=7}$

$4y-9z=17$

$\begin{bmatrix}2x+2y+z=7\\ 3z=-3\\ 4y-9z=17\end{bmatrix}$

Rearranging the equations

$\begin{bmatrix}2x+2y+z=7\\ 4y-9z=17\\ 3z=-3\end{bmatrix}$

solve $3z=-3$ for z:

$z=-1$

$\mathrm{For\:}4y-9z=17\mathrm{\:plug\:in\:}z=-1$

solve $4y-9\left(-1\right)=17$ for y:

$4y-9\left(-1\right)=17$

$4y+9=17$

$4y=8$

$y=2$

$\mathrm{For\:}2x+2y+z=7\mathrm{\:plug\:in\:}z=-1,\:y=2$

solve $2x+2\cdot \:2-1=7$ for x:

$2x+2\cdot \:2-1=7$

$2x+3=7$

$2x=4$

$x=2$

Therefore, the solutions to the system of the equations by the elimination method will be:

$x=2,\:z=-1,\:y=2$
