Some equations have the form y=kx, where k is a number.

which equation cannot be written in the form y=kx?

Hello from MrBillDoesMath!

y = x - 7

Discussion:

Let's step through the answers one-by-one:

y/6 = x             => multiply both sides by 6

y = 6x

y = kx where k = 6

y/x = 1/2          => multiply both sides by x

y = (1/2) x

y = kx where k = 1/2

y = -0.5x

y = kx where k = -0.5

BUT y = x -7 cannot be written simply as y = kx because of the -7 term.

Thank you,

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

answer: 5
