Which is an equation of the line that passes through (–1, –5) and (–3, –7)?
a)
y = 2x + 4
b)
y = x – 4
c)
y = –2x + 4
d)
y = –x – 4

For this case we have that by definition, an equation of the line of the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points through which the line passes, then we find the slope:

Then, the equation is of the form:

We substitute a point and find b:

Finally we have:

y = x-4

Option B

Option b)

Step-by-step explanation:

The equation of a line in the intersecting slope form has the following form:

Where

m is the slope

 Where and  are two points that belong to the line

In this case the points are:  (–1, –5) and (–3, –7)

So:

Therefore

Finally the equation of the line is:

(-1,-0.5)

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
