EQUATIONS OF HORIZONTAL AND VERTICAL LINES

In general, linear equation is a function whose graph is a straight line and it is typically written as 

y = mx + b,

where m is the slope and b is the y-intercept. 

An horizontal lines goes left and right and its equation is in the form of 

y = b,

where b represents the y-intercept.

vertical line goes up and down and its equation is in the form of 

x = a,

where a represents the shared x-coordinate of all points.

Example 1 : 

Write the equation of the line that passes through (-1, 2)  and (3, 2).

Solution :

Plot (-1, 2) and (3, 2).

Connect with a straight line.

Equation of the line is y = 2. 

Example 2 : 

Write the equation of the line that passes through (-2, 3)  and (-2, 1).

Solution :

Plot (-2, 3) and (-2, 1).

Connect with a straight line.

Equation of the line is x = -2. 

Example 3 : 

Write the equation of the line that passes through (0, -4)  and (4, -4).

Solution :

Plot (0, -4) and (4, -4).

Connect with a straight line.

Equation of the line is y = -4. 

Example 4 : 

Write the equation of the line that passes through (0, 5)  and (0, -3).

Solution :

Plot (0, 5) and (0, -3).

Connect with a straight line.

Equation of the line is x = 0.
