Answer:

The equation in point-slope is
\mathbf{y+5=3(x-6)}

Explanation:

We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line
y=-(1)/(3)x+4

The general form of point-slope is;
y-y_1=m(x-x_1)

where m is slope and
(x_1,y_1) is the point

We need to calculate slope.

We are given equation of line
y=-(1)/(3)x+4 that is perpendicular to the required line.

The equation is given in slope-intercept form
y=mx+b where m is slope.

Comparing both equations we get m= -1/3

But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e
m=-(1)/(m)

So, slope of required line is m = 3 (opposite reciprocal of -1/3)

Now, the equation in point-slope form having slope m=3 and point (6,-5) is


y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)

So, The equation in point-slope is
\mathbf{y+5=3(x-6)}
