What is the equation of a horizontal line passing through the point (−7, 5)?

y = 5
y = −7
x = 5
x = −7

Answer 1

y = 5
............................

Answer 2

y=5

Explanation:

Hello

I think I can help you with this

Step 1

In mathematics and applied sciences the slope is the inclination of a linear, natural or constructive element with respect to the horizontal, in this case the line is horizontal , so, m=0

If you know the slope m of a line and the coordinates (x 0, and y0) of a point on the line, you can write the equation of the line in the point-slope form.

`y-y_(0)=m(x-x_(0))`

Let

`P1(-7,5)\\x_(0)=-7\\y_(0)=5\\m=0`

`y-y_(0)=m(x-x_(0))\\y-5=0(x-(-7))\\y-5=0(x+7)\\y-5=0\\y=5\\`

the equation of the lines is

y=5

Have a great day.
