1. Answer: y = -5 – 1/2 x

   Step-by-step explanation:

   Slope intercept form: y=mx+b

   2x+4y=-20

   Isolate the y.

   4y=-20-2x

   Divide by 4.

   y=-20/4-2x/4

   y = -5 – 1/2 x

2. To put the equation 2x + 4y = -20 into slope-intercept form, we need to rearrange the terms in the equation so that the y-term is on the left-hand side and the constant term is on the right-hand side. We can do this by subtracting 2x from both sides of the equation:

   4y = -20 – 2x

   Then, we can divide both sides of the equation by 4 to find the slope:

   y = -5 – (1/2)x

   This is the slope-intercept form of the equation, where the slope is -5/2 and the y-intercept is -5. The slope-intercept form of the equation is:

   y = -5/2x – 5

   Simplifying the fraction gives us the final form of the equation:

   y = -5/2x – 5
   = -2.5x – 5
