Use the matrix method to solve the system of equations 2x + 4y = 8 and 6x + 3y = -3. The resulting matrix is:
nikklg [1K]
So we are given the system:
2x+4y=8\\
6x+3y=-3
Written in matrix form we get:
\left[\begin{array}{cc}2&4\\6&3\end{array}\right] 
  \left[\begin{array}{c}x\\y\end{array}\right] =
\left[\begin{array}{c}8\\-3\end{array}\right]
We compute the solution like this:

  \left[\begin{array}{c}x\\y\end{array}\right] =
 \left[\begin{array}{cc}2&4\\6&3\end{array}\right] ^{-1}
\left[\begin{array}{c}8\\-3\end{array}\right]  \\=
\left[\begin{array}{cc}-3&4\\6&-2\end{array}\right]
\left[\begin{array}{c}8\\-3\end{array}\right] \dfrac{1}{18}\\=
\left[\begin{array}{c}2\\-3\end{array}\right]
The solution is :
\left[\begin{array}{c}2\\-3\end{array}\right]

Determine the equation of the line that is parallel to y=23x+4 and passes through the point (3,7).
Licemer1 [7]

Answer:  y = 23x - 62

<u>Step-by-step explanation:</u>

Parallel lines have the same slope.

y = 23x + 4

  m=23   b=4

Input x = 3, y = 7, & m = 23 into the Point-Slope formula to find the equation or the Slope-Intercept formula to find b (you already have m).  I will choose the latter.

 y = mx + b

 7 = 23(3) + b

 7 = 69 + b

-62 = b

m = 23, b = -62  -->  y = 23x - 62
