Answer:
Substitute the slope and the coordinates of point P in y = mx + b and then solve for b for each equation.
Step-by-step explanation:
Answer:
k = 5
Step-by-step explanation:

Now comparing left hand side & right hand side ,

Cancelling x^2 & 6 from both left hand side & right hand side ,
kx = 5x
=> k = 5
If one of the points is (0,36), then that shows that, that is the number where the line crosses the y-axis, so now all you have to do is plug in 36 to b in the y=mx+b formula. So the answer is B
Answer:
Dimensions of the tabletop is 2.8 cm × 2.8 cm.
Step-by-step explanation:
From the picture attached,
ABCD is a tabletop with leaves AEG, BEF, CFH and GDH.
Dimensions of the tabletop ABCD,
Length = AB
Width = BC
Coordinates of A → (1, 3)
Coordinates of B → (3, 5)
Coordinates of C → (5, 3)
Coordinates of D → (3, 1)
Length of segment = 
AB = 
= 
= 
≈ 2.8 units
BC = 
= 
= 
= 2.8 units
Therefore, dimensions of the tabletop is 2.8 cm × 2.8 cm.
