Answer:
See attachment for what the graph looks like.
Step-by-step explanation:
When you graph these equations, convert 4x+8y=16 into slope-intercept form, which should be y= -1/2x+2.
In this case, 2 is the y-intercept, the part of the line that intercepts with the y-axis, with a negative (goes downward) slope of 1/2.
The line should intersect at (0,2) and have a slope of -1/2.
