Question

Write the equation of a line with an undefined slope and point (1, 7).

y = 7

x = 7

y = 1

x = 1

Answer 1

The equation of straight line is x = 1

Explanation:

Step :-

The equation of straight line having slope 'm' and passing through the point

`(x_(1) ,y_(1) )` is
`y-y_(1) = m (x-x_(1) )`

Slope of horizontal line(that is x-axis) is m = 0

slope of vertical line (that is y-axis) is m is not defined

The equation of straight line having slope is not defined and passing through the point (1,7).

`y-7 = (1)/(0) (x-1)`

cross multiplication we will get equation

`(y-7)(0)=1(x-1)`

x-1 = 0

The equation of straight line is x = 1
