Determine whether LINE AB and LINE CD are parallel, perpendicular, or neither. A(−1, −4) , B(2, 11) , C(1, 1) , D(4, 10) ( write parallel, perpendicular, or neither

Step-by-step explanation:

Hey there!

The points of line AB are; (-1,-4) and (2,11).

Note:

~ Use double point formula.

~ Keep all values.

~ Simplify it.

Therefore this is the equation of line AB.

Now, Finding the equation of line CD.

Given;

The points of line CD are; (1,1) and (4,10).

~ Using formula.

~ Keep all values.

~ Simplify it.

Therefore, 3x - y- 2 = 0 is the eqaution of line CD.

Use condition of parallel lines.

m1= m2

Slope of equation (i)

Therefore, m1 = 5

Slope of second equation.

Therefore, m2 = 3.

Now, m1≠m2.

So, the lies are not parallel.

Check for perpendicular.

m1*m2= -1

3*5≠-1.

Therefore, they aren't perpendicular too.

So, they are neither.

Hope it helps...
