We are asked to find the equation of a line that is perpendicular to the line y = 2x - 3 and passes through the point (6, 4)

Recall that the equation of a line in slope-intercept form is given by


y=mx+b

Where m is the slope and b is the y-intercept.

Comparing the general form with the given equation we see that the slope is 2

Since we are given that the lines are perpendicular so the slope of the other line must be negative reciprocal of the given line.


\begin{gathered} m=-(1)/(m_1)_{}_{} \\ m=-(1)/(2) \end{gathered}

So, the slope of the required equation is m = -1/2

Since we are also given that the line passes through the point (6, 4)

The point-slope form of the equation of a line is given by


(y-y_1)=m(x-x_1)_{}

Let us substitute the slope and the given point into the above equation and simplify the equation.


\begin{gathered} (y-4)=-(1)/(2)(x-6)_{} \\ y-4=-(1)/(2)x+3 \\ y=-(1)/(2)x+3+4 \\ y=-(1)/(2)x+7 \end{gathered}

Therefore, the equation of the line is


y=-(1)/(2)x+7
