What is the slope of a line perpendicular to the line whose equation is 2y=-6x+8
1)-3
2)1/3
3)1/6
4)-6

2y=-6x+8

First, the slope of any equation, is always the coefficient with the variable "x".

So, the slope for this line, is -6x.

To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.

2y=-6x+8

      2

y=-3+4

Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.

And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to  1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.

The answer is 2) 1/3.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
