Answer:
The final equation is
Explanation:
The slope of the line CB where, C(0,3) and B(12,-6) will be
Now, if the line perpendicular to the line CB has slope N, then M × N = - 1
⇒
{Since
}
Now, equation of the straight lines which are perpendicular to CB will be in slope-intercept form
{Where, c is the y-intercept}
If this straight line passes through the point (7,4), then
⇒ 12 = 28 + 3c
⇒ 3c = - 16
⇒
Therefore, the final equation is
