Question

Need help asap answering no 2 and 4

Answer 1

Remark

Start by finding the slope of AB.

Then find the slope of CD. If the slopes are the same, you have parallel lines.

Step One

Find the slope of AB

y2 = 7

y1 = 3

x2 = -3

x1 = -7

Formula

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

Solve

m = (7 - 3) / (-3 - - 7)

m = 4/(-3 + 7) = 4/4 = 1

Step Two

Repeat Step One for CD.

Givens

y2 = - 5

y1 = - 1

x2 = 1

x1 = 5

m = (-5 - - 1)/(1 - 5)

m = (-5 + 1)/(-4)

m = - 4/-4 = 1

Conclusion

Since the lines have the same slope, they are parallel.

I can't see number 4

Answer 2

For 2, AB is parallel to CD as AD is also parallel to BC

For 3, you can also say AD is parallel to BC
