Question

Write the equation of the line that satisfies the given conditions. Express the final equation in standard form.

contains the point (–10, –7) and is perpendicular to the y axis
a. x = –7
b. x + y = –7
c. y = –7
d. x – y = –10
e. y = -10

Answer 1

The equation of line with given points and perpendicular to y-axis is

y = - 7

Explanation:

Given as :

The given points as ( - 10 , - 7)

The equation of line is Y = mX + c

So The line will satisfy given points

Or, - 7 = m ( -10 ) + c

Now This line is perpendicular to y- axis

∴ The slop of line perpendicular to y axis is 0

So, - 7= 0 + c

or, c = - 7

∴ Equation of line is y = 0 + c

Or, y = - 7

Hence The equation of line with given points and perpendicular to y-axis is y = - 7 Answer
