Answer:

A sphere

Step-by-step explanation:

A cross section of a three dimensional figure is the surface or intersection of the three dimensional figure and a plane, it is the shape obtained by cutting straight through the three dimensional figure

The shape of an inclined cross section of a cube can be a triangle however, he shape of a horizontal and inclined cross section of a sphere is a circle.

Compare the line passing through the points (−3, − 11) and (6, 4) to the line given by the equation y=32x−6.
butalik [34]

Answer:

See below

Step-by-step explanation:

<u>Given points:</u>

  • (-3, -11) and (6, 4)

<u>Let's calculate it's equation:</u>

  • y = mx +b
  • m = (4 + 11)/(6 +3) = 15/9 = 5/3
  • y = 5/3x + b
  • -11 = 5/3*(-3) + b ⇒ b = -11 + 5 = -6
  • y = 5/3x - 6

<u>The given line:</u>

  • y = 32x - 6

Compared, the lines have different slope (5/3 vs 32) but same y- intercept (-6), so both pass through the point of (0, -6). y= 32x - 6 has greater rate of change.

Write an equation in point-slope form of the line that passes through the point (4,7) and has a slope of -1.
creativ13 [48]

Answer:

y - 7 = - 1(x - 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 1 and (a, b) = (4, 7) , thus

y - 7 = - (x - 4)
