For this case we have the following equation of a line, of the point-slope form:

$y-4 = \frac {3} {4} (x + 8)$

We want to write the equation of the standard form:

y = mx + b

To do this, we manipulate the first equation:

$y-4 = \frac {3} {4} x + \frac {3} {4} *8\\y-4= \frac {3} {4} x + 6\\y = \frac {3} {4} x + 6 + 4\\y = \frac {3} {4} x + 10$

Thus, the equation in its standard form is given by:

$y = \frac {3} {4} x + 10$

Answer:

$y = \frac {3} {4} x + 10$
