In Exercises 19 and 20, determine whether the lines AB and CD are parallel.20. A(2, 3), B(2, −2) and C(−2, 4), D(−2, 5)

To determine
Whether the lines AB and CD are parallel or not.

Explanation

Given:

The points are A(2,3) , B(2,2) , C(2,4) and D(2,5)

Formula used:

The formula to calculate the slope of the equation of line is,

m=y2y1x2x1 (1)

Calculation:

The condition of two lines to be parallel is,

m1=m2

Or the slopes are undefined.

The slope of the line AB is,

Substitute 2 for y2 , 3 for y1 , 2 for x2 , 2 for x1 in equation (1)
