Y= 2x+5
According to the slope int. formula,
y=mx+b
here, slope, m=2
y int, b =5
so, the equation is y=2x+5
Um 4.2 maybe since -4.2 and 4.2 or on the opposite scale
Answer:

Step-by-step explanation:
Using k as the constant of proportionality.
The expression that expresses the relationship : p varies jointly with the square of d and the cube of u.
Varies jointly means that p will change as 'd' and 'u' will change together with respect to their powers.
We get the expression as:

Answer:
11.7
