Dunno what the work backward way is
seeems hard
maybe it's trial and error?
anyway

2n+5<13
minus 5 both sides
2n<8
divide by 2
n<4
X = 2 means for whatever y value you select the x value will be 2. So if you graph a couple of coordinates it becomes quickly evident that x = 2 is a vertical line that crosses the x axis at 2.
Answer:
Slope = -2
Step-by-step explanation:
Since, slope = 
Rise = -(y-intercept)
Run = (x-intercept)
From the graph attached,
y - intercept = -(4) = -4
x - intercept = 2
Therefore, slope the line given in the graph attached will be,
Slope =
= -2
Slope = -2
