The equation of Straight line, perpendicular to line [k]would be y = - x + 5

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of straight line also represents the directly proportional relation as -

y = mx + c

y = mx         {c = 0}

m = y/x    

or

m = Δy/Δx  

where [m] is constant of proportionality.

We have a line [k] that has an equation of y = x - 7

We have the given equation of line -

y = x - 7

Slope of line will be 1.

Slope of the line perpendicular to line [k] will be -

m[p] = -1

Then, the general equation would become -

y = - x + c

For point (7, - 2), we can write -

- 2 = - 7 + c

c = - 2 + 7

c = 5

Therefore, the equation of Straight line, perpendicular to line [k]would be y = - x + 5
