Answer: Choice H
y = -2x+3
=========================================================
Explanation:
Start at any point you want on the diagonal line. Notice how we move down 2, right 1 to get to a neighboring point. This "down 2, right 1" motion determines the slope
- rise = go down 2 units
- run = go right 1 unit
slope = rise/run = -2/1 = -2
So m = -2 is the slope
Another way to find the slope is to use the slope formula for any two points on that diagonal line.
The y intercept is 3 because this is where the diagonal line crosses the y axis. This means b = 3.
---------------------
To summarize, we found that m = -2 is the slope and b = 3 is the y intercept.
We go from y = mx+b to y = -2x+3
