Answer:
YES you are right
Step-by-step explanation:11 squared equals 121
I)
The Midpoint M of the line segment AB is found using the Midpoint formula:

ii)
the slope of the line through A and B is found by the slope formula:

iii)
the product of the slopes of 2 perpendicular lines is -1, so the slope of the line perpendicular to the line through A and B is -1/(-1)=1
iv)
the equation of the line with slope 1, which contains point M(3, 9) is found by the slope point form equation of a line:
y-9=1(x-3)
y-9=x-3
y=x+6
Answer: y=x+6
Can you show the pairs of variables?
Answer:
C. Graph c
Step-by-step explanation:
I got it correct
80*x + 210 = 490 ;
80*x = 280 ;
x = 280÷80 ;
x = 3.50 ;
