Find the midpoint of segment LK with endpoints L(-2, 4) and K(5,3).
fenix001 [56]
Answer: (1.5, 3.5)

Explanation:
Find the slope by using the coordinates for points L and K.

3 - 4 = -1
5 - (-2) = 7
Slope = -1/7

Then you plot your points on the graph.
But you want to half your slope to find the midpoint. So your slope would now be -0.5/3.5.

And when you follow that slope, you will plot down the coordinate (1.5, 3.5), which is the midpoint.

Hope this helped! :3

Which equation represents a proportional relationship? Y=-5(x+1). Y=5x+1. Y=-x. Y=1/5x
Tema [17]
A proportional relationship is also a direct variation.
The general equation of direct cvariation is

y = kx,

where k is a number.

In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as

y = -x

What is the surface area of the square pyramid below?
Reika [66]

The surface area of square pyramid is the sum of the area of all its sides.

If l is the slant height and base is s each then surface area of pyramid is given by:

Surface area = s2+2xsx l

From the given figure in the question:

S=6 cm ,l= 8cm.

Substituting these values in surface area formula we have:

Surface area = 62+2x6x8

Surface area = 36+96

Surface area =132cm2
