Question

What is an equation of the line that passes through the points (7, 4) and (-5, 4)

Answer 1

Equation of the line that passes through the points (7, 4) and (-5, 4) is

`y=4`

Explanation:

Equation of line in two point form is given as

`y-y_1=(y_2-y_1)/(x_2-x_1) (x-x_1)` ----------(1)

Here

`(x_1, y_1) = (7, 4) \ \ \ and \ \ \ (x_2, y_2)=(-5, 4)`

Substituting values in equation (1)

`y-4 =(4-4)/(-5-7) (x-7)`

`y-4 =0`

`y=4`
