What is the value of y?
10 + 2x

-5 see below

Step-by-step explanation:

If 2x  

the x part you wrote wrong and is supposed to be y then...

10+2y

10=-2y

-5=y

If we are talking about the slope the answer is -2

Step-by-step explanation:Change the equation the slope intercept form, y=Mx+b, where m is the slope and b is the y intercept

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
