Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.

Help with the linear equations

IgorC [24]

Answer:

$y \: intercept = - 1 \frac{1}{2}$

Step-by-step explanation:

The y intercept form for the equation of a line is

$y = mx + c$

You should note that c represents the y-intercept of the line (where the line touches the y-axis)

$y = mx + c \\ \\ we \:were\: given \:the \:equation \:y = x - \frac{3}{2} \\ \\ therefore \: the\: value \:of \:c \:is\: - \frac{3}{2} \:or -1 \frac {1}{2}$
