Use the following graph to answer questions 1-3.

mart [117]

Answer:

m = 7/5

b = 7

y = 7/5x + 7

Step-by-step explanation:

points (-5,0) (0,7)

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

= (7-0)/(0--5)

= (7-0)/(0+5)

= 7/5

y intercept = point where it crosses the y axis (0,7)

y = mx+b

m = 7/5

b = 7

y = 7/5x + 7

•given ABCD is a kite, check every box that must be true

natali 33 [55]

Answer:

Step-by-step explanation:

A kite is a quadrilateral made up of two isosceles triangles. A kite does not have any parallel side, but has two pairs of equal adjacent sides. All four sides are not congruent, only two pairs of consecutive sides are congruent.

The vertices of a kite are right angles. The diagonals bisect each other at right angles ( that is they are perpendicular). Therefore the following are true:

1) two pairs of consecutive sides are congruent

2) The diagonals are perpendicular

3) The diagonals bisect each other.

Point A= (3,6), B = (5,0), C= (-2,-4) D = (-3,4)

$AB=\sqrt{(0-6)^2+(5-3)^2}=\sqrt{40} \\AD=\sqrt{(4-2)^2+(-3-3)^2}=\sqrt{40}\\ BC=\sqrt{(-4-0)^2+(-2-5)^2}=\sqrt{65}\\ DC=\sqrt{(4-(-4)^2)+(-3-(-2))^2}=\sqrt{65}$

AB=AD, BC = BC.

This is a kite since two pairs of consecutive sides are congruent
