Answer: I can't answer question #4 as there is no graph or sufficient information provided, however, here are the answers for #5
#5.
Step 1 : 7
Step 2 : 0,0
Step 3 : (1,7) any other point plotted on that line would work as there is no slope, and therefore, no second pt.
Step 4 : Draw Arrows at the end of the points references
Explanation:
Step 1 : Slope intercept is in the form of
where b represents the y-value when x = 0. Since there is no x-value, the b value just ends up being the quantity present which is seven.
Step 2 : Since there is a slope of 0, and it just a horizontal line across the pt y = 7, there is no rise and no run and you can use 0 or none to represent that .
Step 3: Just find another point that lies on the horizontal line. I found the one closest to y=7 in the positive x direction.
Step 4: Lastly just draw a horizontal line connecting the two points and arrows facing the opposite direction.
