Here are the equations of the two lines based on the given points:

1. Line 1 (through points $(3, 1)$ and $(0, -3)$): $y = 1.33x - 3$

   • Slope ($m$): 1.33
   • Intercept ($b$): -3

2. Line 2 (through points $(-1, -5)$ and $(4, -2)$): $y = 0.6x - 4.4$

   • Slope ($m$): 0.6
   • Intercept ($b$): -4.4

Here are five related questions:

1. How do you find the slope of a line from two points?
2. How can you verify if a point lies on a line equation?
3. What is the difference between slope-intercept and point-slope form?
4. How do parallel lines relate in terms of their slopes?
5. What is the geometric interpretation of the y-intercept?

Tip: The slope of a line represents the rate of change of y with respect to x, or the steepness of the line.
