Alex

Answer:

The answer is -2

Step-by-step explanation:

First we divide 12 by 6.

12/6 = 2

Next we subtract 3 by 4.

3 - 4 = -1

Now we solve.

-1 * 2 = -2

So, the answer is -2.

Hope this helps! :)

Write an equation of a line that passes through (0 -5) and (2, -5)
Ivan

Answer:

The line would be a horizontal line through the point y = -2

The equation of the line would therefore be

y

=

−

2

Explanation:

If graph the point

(

0

,

−

2

)

we find that that point is on the y axis and therefore represents the y intercept.

If we then plug in the slope and y intercept into the slope-intercept formula of

y

=

m

b

+

b

where

m

=

the slope the

b

=

the y intercept, then

y

=

m

x

+

b

becomes

y

=

0

x

+

(

−

2

)

which simplifies to

y

=

−
