Following is the text part of the solution. Please see the attached file for complete solution. Equations, diagrams, graphs and special characters will not appear correctly here.
==============================================

Hint:

Always remember, if you have written the equation of a line as y = mx + c, the sign of the slope 'm' and the intercept 'c' gives you how the line is oriented.

If m is positive, line is slanted to the right
If m is negative, line is slanted to the left
If c is positive, the line will meet the y-axis in the positive side (+ y axis)
If c is negative, the line will meet the y-axis in the negative side (- y axis)

(2)

4x + 3y = 12

Lets rewrite this equation in the form of y = mx + c

3y = 12 - 4x
y = 4 - 4/3 x

y = -4/3 x + 4, negative slope = -4/3, positive intercept=4

Answer = B ...
