Which pair of points will determine a line

Mathematics

irina [24]3 years ago

For a pair of points to be parallel to the x-axis, the points have to consist the same x-coordinates.

In this case, only (1) (2,3), (2,-5) have the same x-coordinates.

Therefore, the answer is (1) (2,3), (2,-5).

Hope it helps!

Answer:

2) (5,4) and (-1,4)

These have the same y so this line will be horizontal making it parallel to the x-axis.

Step-by-step explanation:

All horizontal lines are parallel to each other.  The x-axis is horizontal. So we are looking for a horizontal line.  On a horizontal line, all the y-coordinates are the same; their equation is in the form y=a number after all.

Anyways we looking for a pair of points with the same y-coordinate.

1) (2,3) and (2,-5)

These have the same x-coordinate so this line is vertical. This would actually be perpendicular to the line given.

2) (5,4) and (-1,4)

These have the same y so this line will be horizontal making it parallel to the x-axis.

3) (2,2) and (-1,-1)

y's aren't the same so not horizontal

x's aren't the same so not vertical

4)  (3,4) and (6,2)

y's aren't the same so not horizontal

x's aren't the same so not vertical

1. A sphere is sliced so that the cross section does not intersect the center of the sphere.
stich3 [128]
1. The shape of cross-section is a circle.
2. The face parallel to ABCD is EFGH. Since this is a a rectangular shape,

A = L*H = 12*6 = 72 cm^2

3. The cross-section parallel to ABC is DEF with h = 12 ft, b= 5ft (where h is the height and b is the base of a right angled triangle).

Area, A = 1/2 *b*h = 1/2*5*12 =30 ft^2

4. Plane BDHF is a rectangle shape whose length is the diagonal of ABCD.

Diagonal BD = sqrt (AB^2+BD^2) = sqrt (8^2+7^2) = 10.63 cm.
Perimeter, P = 2(BD+DH) = 2(10.63+6) = 33.26 cm
