So you express fraction.
15 x (1/3)^ 3=15/27=5/9
Add -3.4 to both sides
-9.3 = y
Hope this helps!
Answer:
2.
Step-by-step explanation:
The gradient or slope of a straight line which is found between two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Where y2 = 7
y1 = 3
x2 = 4
x1 = 2
=> m = (7 - 3) / (4 - 2)
m = 4 / 2 = 2
The gradient is 2.
#3 is not a function because there are two answers for one out put
#4 is a function because it is a straight line
It would be 1/6...
Hope i have done things for you
