Answer:
3 and - 4
Step-by-step explanation:
Calculate the gradients using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
Line A
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m =
= 3
Line B
with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (0, 5) ← 2 points on the line
m =
=
= - 4
Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
=
%
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
=
%
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because,
Therefore, Option B and F is correct only.
Answer:
The graph shows a relation and a function
Step-by-step explanation:
Because there is one value of y for every value of x, this is a relation and a function.
