Step-by-step explanation:

Given equation of line is:

[tex] 2x + y = 3\\\\ \therefore y = - 2x + 3\\\\\[/tex]

Equating it with[tex] y = m_1x+c [/tex] we find:

[tex] m_1=-2m [/tex]

Let the slope of required line be [tex] m_2 [/tex]

[tex] \because [/tex] Required line is parallel to the given line.

[tex] \therefore\: m_2=\frac{-1}{m_1}=\frac{-1}{-2}=\frac{1}{2}[/tex]

[tex] \because [/tex] Required line passes through (5, 4) and has a slope [tex] m_2=\frac{1}{2}m [/tex]

[tex] \therefore [/tex] Equation of line in slope point form is given as:

[tex] y - y_1 = m_2(x-x_1) \\\\ \therefore y- 4=\frac{1}{2}(x-5)\\\\ \therefore y- 4=\frac{1}{2}x-\frac{5}{2}\\\\ \therefore y=\frac{1}{2}x+4-\frac{5}{2}\\\\ \therefore y=\frac{1}{2}x+\frac{2\times 4-5}{2}\\\\ \therefore y=\frac{1}{2}x+\frac{3}{2}\\\\

\therefore 2y= x +3\\\\

\therefore x -2y + 3=0 \\[/tex]

Hence, x -2y + 3=0 is the required equation of line.

Answer:

  x -2y = -3

Step-by-step explanation:

The line perpendicular to

  ax +by = c

through point (h, k) can be written as ...

  b(x -h) -a(y -k) = 0 . . . . . swap x and y coefficients, negate one of them.

Putting this in standard form gives ...

  bx -ay = bh -ak

For a=2, b=1, and (h, k) = (5, 4), this is ...

  x -2y = 5 -2(4) = -3

  x -2y = -3

_____

The graph shows the two lines and the point.
