Find the slope and the y-intercept of he line with the equation 2y+x=-6

The slope is -1/2 and  the y intercept is -3

Step-by-step explanation:

To find the slope and the y intercept, we need to get it in the form

y= mx+b  where m is the slope and b is the y intercept

Solve for y

2y+x = -6

Subtract x from each side

2y+x-x = -x-6

2y =-x-6

Divide by 2

2y/2 = -1/2x -6/2

y = -1/2x -3

The slope is -1/2 and  the y intercept is -3

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
