First rewrite into 2 inequalities,

-2\lt3x+4

3x+4\lt31

Solve each of the inequalities,

-2\lt3x+4\implies3x\gt-6\implies x\gt-2

3x+4\lt31\implies 3x\lt27\implies x\lt9

So our x is between -2 and 9 which can be written as,

-2\lt x\lt9

or as an interval,

x\in(-2,9)

Hope this helps :)

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

y = mx+b

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

(0,1)\\(1, -2)

We found the slope:

m = \frac {y2-y1} {x2-x1}\\m = \frac {-2-1} {1-0} = \frac {-3} {1} = - 3

So, the equation is of the form:

y = -3x + b

We substitute a point to find "b":

1 = -3 (0) + b\\1 = b

Finally, the equation is:

y = -3x+1
