Answer:
-1/2
Step-by-step explanation:
y2-y1 = -5-0 =-5
x2-x1 = 8-(-2)=10
-5/10= -1/2
Answer:
k = 3
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition y = - 6 when x = - 2, then
k = = = 3
The answer in scientific notation is 9.345 x 10^2
