Endpoints of segment MN have coordinates (0, −3), (−2, −4). Endpoints of segment AB have coordinates (2, 5), (4, k).

What value of k makes these segments parallel?

Answer:

The value of k is 6

Explanation:

we know that

If two segments are parallel, then their slopes are the same

we know that

The formula to calculate the slope between two points is equal to


m=(y2-y1)/(x2-x1)

step 1

Find the slope MN

we have

M(0, −3), N(−2, −4)

substitute


m=(-4+3)/(-2-0)


m=(-1)/(-2)


m=0.5

step 2

Find the slope AB

A(2, 5), B(4, k)

substitute in the formula


m=(k-5)/(4-2)


m=(k-5)/(2)

Remember that the slopes MN and AB must be equal


0.5=(k-5)/(2)

Solve for k


1=k-5


k=1+5=6

therefore

The value of k is 6
