The intercepts can be found by setting the other variable to zero and dividing by the coefficient of the variable of interest. This tells you the x-intercept is -2/3, and the y-intercept is -2/1 = -2. The y-intercept is conveniently on a grid point. To find other grid points on the line, it is convenient to choose integer values for x, then solve for y.
y = -3x -2
Positive values for y will require negative values of x.
Answer:
Is to give us a range of values for our estimated population parameter rather than a single value or a point estimate.
Step-by-step explanation:
Assuming:

subtract a from both sides

multiply both sides by 5

divide both sides by 3

____________________
if,

multiply both sides by (5+a), then divide both sides by 3
