Answer:

B & C

Step-by-step explanation:

A proportional relationship has a proportionality constant (constant rate of change) and and must cross through the origin (or begin at (0,0). This means it's y-intercept is 0. Each of the options is a linear function. All of the functions have a constant rate of change. Only one as b=0 or 0 as the y-intercept.

B) y=4x has a constant of 4 and passes through the origin.

C) y=7x has a constant of 7 and passes through the origin.

The table represents a linear equation. Which equation correctly uses point (–2, –6) to write the equation of this line in point

sineoko [7]

Answer:

$y+6=m(x+2)$

where I would have to look at the table to know $m$ .

Step-by-step explanation:

Point-slope form of a line is

$y-y_1=m(x-x_1)$

where $m \text{ is the slope and } (x_1,y_1) \text{ is a point on that line}$

You are given $(x_1,y_1)=(-2,-6) \text{, but no value for }m$ .

So we know we are looking for an equation that looks like this:

$y-(-6)=m(x-(-2))$

If you simplify this looks like:

$y+6=m(x+2)$

lidiya [134]

A= P(1 + r)^n
where,
A= final balance
P= initial quantity
n= number of compounding periods
r= percentage interest rate
So,
P= $200
n= 6 years
r= 6%= 0.06

=$200(1 + 0.06)^6
=$283.70
