1. Problem Description

The problem asks us to find the equation of a line that passes through the point (3,3)(3, 3) and is perpendicular to the line 5x6y=45x - 6y = 4.

2. Solution Steps

First, we need to find the slope of the given line 5x6y=45x - 6y = 4. To do this, we can rewrite the equation in slope-intercept form, y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.
5x6y=45x - 6y = 4
6y=5x+4-6y = -5x + 4
y=56x+46y = \frac{-5}{-6}x + \frac{4}{-6}
y=56x23y = \frac{5}{6}x - \frac{2}{3}
So, the slope of the given line is m1=56m_1 = \frac{5}{6}.
Since we want a line that is perpendicular to the given line, the slope of the new line, m2m_2, must be the negative reciprocal of m1m_1.
m2=1m1=156=65m_2 = -\frac{1}{m_1} = -\frac{1}{\frac{5}{6}} = -\frac{6}{5}
Now we know the slope of the new line, m2=65m_2 = -\frac{6}{5}, and a point it passes through, (3,3)(3, 3). We can use the point-slope form of a linear equation, which is:
yy1=m(xx1)y - y_1 = m(x - x_1)
where (x1,y1)(x_1, y_1) is the given point. Plugging in our values, we have:
y3=65(x3)y - 3 = -\frac{6}{5}(x - 3)
y3=65x+185y - 3 = -\frac{6}{5}x + \frac{18}{5}
y=65x+185+3y = -\frac{6}{5}x + \frac{18}{5} + 3
y=65x+185+155y = -\frac{6}{5}x + \frac{18}{5} + \frac{15}{5}
y=65x+335y = -\frac{6}{5}x + \frac{33}{5}

3. Final Answer

y=65x+335y = -\frac{6}{5}x + \frac{33}{5}
