Y varies inversely with x if y = 7 when x =-4, find y when x = 5

y = -

Step-by-step explanation:

Given y varies inversely with x then the equation relating them is

y = ← k is the constant of variation

To find k use the condition y = 7 when x = - 4, then

7 = ( multiply both sides by - 4 )

- 28 = k

y = ← equation of variation

When x = 5 , then

y = = -

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
