Use a transformation to solve the equation.

k/-4 = - 0.8

A.

k = - 3.2

B.

k = - 0.2

C.

k = 0.2

D.

k = 3.2

k/-4 = - 0.8,

make k the subject of the equation by multiplying through by - 4,

this means, (k/-4) x - 4 = - 0.8 x - 4

this should give you k = - 0.8 x - 4, the negatives will cancel out to give you positive values,

so k = 3.2

your answer is D
