Chapter 3: Q 3.62. (page 288)

Find an equation of a line perpendicular to the line $y = \frac{1}{2} x - 3$ that contains the point $(6, 4)$ . Write the equation in slope-intercept form.

Short Answer

Expert verified

The equation is $y = - 2 x + 16$

Step by step solution

Step 1. Find the slope of the given line

The given line is:

$y = \frac{1}{2} x - 3$

The line is in slope-intercept form. Therefore, its slope is:

$m = \frac{1}{2}$

Step 2. Find the slope of the perpendicular line and identify the point

The slopes of perpendicular lines are negative reciprocals.

Therefore, the slope of the perpendicular line is:

$m_{1} = - 2$

And the given point is $(6, 4)$ .

$(x_{1}, y_{1}) = (6, 4)$

Step 3. Substitute the values into the point-slope form

The point-slope form is:

$y - y_{1} = m (x - x_{1}) y - 4 = - 2 (x - 6) y - 4 = - 2 x + 12$

Step 4. Write the equation in slope-intercept form

The slope-intercept form of the perpendicular line is $y = - 2 x + 16$ .
