What is the slope for the line AB if A(4,-7) and B(-2,-7)?

Slope: 0

Step-by-step explanation:

We have to find the slope of the line with the given points.

To find the slope, we would use the slope formula: m = y2-y1/x2-x1, where as "m" is the slope.

Plug in your coordinates and solve.

Solve:

m = -7 - (-7)/-2 - 4

m = -7 + 7/-2 - 4

m = 0/-6

Divide -6 from 0.

m = 0

You would notice that we have a "0" in our slope. There is no "rise" in the slope.

This means that the slope of our line would be 0.

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'.
