Question

For each equation, determine whether x and y are directly proportional that is, if the equation shows direct variation)If so, then find the constant of proportionality (the constant of variation),3(a) y 8x+1(b) yХProportionalConstant of proportionality: k []ProportionalConstant of proportionality:Not proportionalNot proportional

Answer 1

Step-by-step explanation:

For direct variation equations, we have the general outlook as:

`a\text{ = }(b)/(d)\cdot c`

What this simply means is that we have to multiply every instance of the independent variable (c in this case) with a constant ratio or proportionality ratio (b/d in this case) to get the instance of the dependent variable (a in this case)

a) For the first equation, we do not have a direct variation. The reason for this is that there is no constant term that relates to the terms of the dependent variable. The correct choice here is non-proportional

b) For the second fu
