Answer:
The given coordinates of the vertices of rectangle ABCD are A(−2,2),B(4,2),C(4,−2).
We are to plot D on the graph.
Since ABCD is a rectangle, the abscissa of D will be that of A and the ordinate of D will be that of C.
Step-by-step explanation:
Answer:
The slope is 4/3
Step-by-step explanation:
Slope is found by using the equation
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are two points
m=(1--3)/(1--2)
= (1+3)/(1+2)
= 4/3
Answer:
2
Step-by-step explanation:
Maybe they got confused or could not read her handwriting well because im pretty sure it is 2
Answer:
Discriminant=8
Step-by-step explanation:
-x²+4x-2=0
here a=-1,b=4 and c=-2
Discriminant=b²-4ac
Discriminant=(4)²-4(-1)(-2)
Discriminant=16-8
Discriminant=8
i hope this will help you :)
