What is the slope of the line that contains the points (-1, 8) and (2, -4)?

-4

Step-by-step explanation:

The slope of a line given two points is given by

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

   = (-4-8)/(2 - -1)

   = (-4-8)/(2+1)

   = -12/3

   = -4

-4

Step-by-step explanation:

Use the equation for slope.

The slop is -4.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
