6. Complete the coordinate proof. Given: A(0,6), B(6,6), C(6,0), D(0,0); ZDAB, ZABC, ZBCD, ZCDA are right angles.
Prove: ABCD is a square.
A square on a coordinate plane
Proof:
AB = V(22 – 21)2 + (y2 – yı) so AB =
.
BC
V (x2 – 21)2 + (92 – yı) so BC =
-
.
CD= V(22 – 21) + (92 – yn) so CD=
=
• DA = V(x2 – 21) + (y2 – yı)? so DA=
.
=

answer: i think it's a

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

ok thats very interesting

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
