X = 57 + √2001/24, 57 - √2001/24
x ≈ 4.23885577, 051114422
Operations with variables can give you excluded values by making the denominator equal to zero.
Ex. 48/60 always equals to 4/5 but 4x/6x is not always equal to 2/3 because when you make x equal to zero it makes the equation invalid.
I'm assuming problem 6 is the graph on the right.
If so, then the slope is 1/2
Start at a point like (0,-1) which is the y intercept. Move up 1 and to the right 2 to arrive at (2,0) which is the x intercept.
The movement pattern "up 1, right 2" determines the slope directly
slope = rise/run = 1/2
rise = 1 = go up 1
run = 2 = go to the right 2
------------------------------
You could also pick two points from the blue line, then use the slope formula. If we picked (0,-1) and (2,0), then
m = (y2-y1)/(x2-x1)
m = (0-(-1))/(2-0)
m = (0+1)/(2-0)
m = 1/2
