Estimating linear equations and inequalities

Reference no: EM13124653

1. Give 3 real-world examples where something is increasing at a constant rate or decreasing at a constant rate. The starting amount would be the y-intercept, "b", and the rate at which it increases would be the slope, "m". Give the equation of the lines for your examples using y = mx + b with your "m" and "b".

2. Why do we have to shade the region above the line for y > mx +b or y > mx + b, and shade below the line for y < mx + b or y < mx + b? Why can't the answer for these linear inequalities be simply the line y = mx + b? Why do we have to do all the shading?
