the equation of the line will be:![y=x-4](/tpl/images/1016/1879/9de4a.png)
Step-by-step explanation:
Equation of line: x + y = 6
We need to write an equation for the perpendicular line that goes through
(5, 1).
The equation will be in slope-intercept form
where m is slope and b is y-intercept
Finding Slope:
Equation of line given is: x+y=6
Writing it in slope-intercept form:![y=-x+6](/tpl/images/1016/1879/9a9ce.png)
The slope of this line is m = -1 (By comparing it with
we get m = -1)
Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e.![m_1=-\frac{1}{m_1}](/tpl/images/1016/1879/b82e4.png)
So, slope of required line will be: m=1
Now, using the point (5,1) and slope m=1 we can find y-intercept
So, we get y-intercept b = -4
Now, the equation of required line, having slope m=1 and y-intercept b = -4
So, the equation of the line will be:![y=x-4](/tpl/images/1016/1879/9de4a.png)
