Answer:

The y-intercept is -9.

Step-by-step explanation:

Using the form y = mx + b, b is the y-intercept of the equation. Thus by definition in the equation y = 1/2x - 9, -9 is the y-intercept.

Additionally, the y-intercept is the point where x = 0; thus, when y = 1/2(0) - 9, y = -9.

I need help plz pt.2

Answer:

See explanation

Step-by-step explanation:

Consider the sequence $\dfrac{1}{32},\ \dfrac{1}{8},\ \dfrac{1}{2}, 2,\ 8,...$

Rewrite it as

$b_1=\dfrac{1}{32},\\ \\b_2=\dfrac{1}{8},\\ \\b_3=\dfrac{1}{2},\\ \\b_4=2,\\ \\b_5=8...$

The points on the coordinate plane are

$(1,b_1),\ (2,b_2),\ (3,b_3),\ (4,b_4),\ (5,b_5),...$ (see attached graph).

Since

$4=\dfrac{b_2}{b_1}=\dfrac{b_3}{b_2}=\dfrac{b_4}{b_3}=\dfrac{b_5}{b_4}...,$ given sequence is geometric.
