Answer :
The equation of the line is x = -7. The equation of the other line is x = -3 and the equation in intercept form is x/-3 = 1
It is given that the x-intercept is at -7. this implies that the line passes through the point (-7,0)
The formula of the slope of the lines is (y₂ - y₁)/(x₂ - x₁) where (x₁ , y₁) and (x₂,y₂) are 2 points the line passes through.
Since the slope of the line is undefined, x₂ - x₁ = 0
This implies that the line is parallel to the y-axis
Hence, the equation of the line is
x = -7.
Here we see that the x-intercept and any other point have the x coordinate of -3.
Hence the equation of the line will be x = -3
The equation of this particular line in slope intercept form is
x/-3 = 1
