To find a line perpendicular, use the opposite-reciprocal slope of the line given. Also, use the point-slope form of a line since you're given a point.

y-7 = 1/10 (x-5)

Simplify to y=mx+b (slope-int) form

y-7= 1/10x -1/2
y = 1/10x + 13/2

Answer:

The equation of line is [tex]y=\frac{1}{10}x+\frac{13}{2}[/tex]

Step-by-step explanation:

To find : What is the equation of a line perpendicular to the line [tex]y=-10x+1[/tex] passing through point (5,7) ?

Solution :

We know that,

When two lines are perpendicular then slope of one line is negative reciprocal of another line.

Let the required line [tex]y=mx+b[/tex]

A line perpendicular to the line [tex]y=-10x+1[/tex]

Slope of the line is [tex]m_1=-10[/tex]  

Slope of the perpendicular line is [tex]m=-(\frac{1}{m_1}=\frac{1}{10}[/tex]  

The passing points of the equation is (5,7)

Substitute in the formula,

[tex]7=\frac{1}{10}(5)+b[/tex]

[tex]7=\frac{1}{2}+b[/tex]

[tex]b=7-\frac{1}{2}[/tex]

[tex]b=\frac{13}{2}[/tex]

Now, substitute [tex]m=\frac{1}{10}[/tex]  and [tex]b=\frac{13}{2}[/tex] in required line.

[tex]y=\frac{1}{10}x+\frac{13}{2}[/tex]

Therefore, The equation of line is [tex]y=\frac{1}{10}x+\frac{13}{2}[/tex]
