This is not a good model because the residual plot becomes thicker on one end.
This is a good model because the residual plot is not an obvious pattern and does not become thicker toward one of the ends.
This is a good model because the residual plot shows an obvious pattern.
This is not a good model because the residual plot has an obvious pattern.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
