How do I find slope intercept for a line that passes through (4,-4) with a slope of -1

Mathematics

Answer:

y = -x

Step-by-step explanation:

Use the equation:

y = mx + b

where m is the slope and b is the y-intercept.

In this case, there is no y intercept, as we can see by manipulating the point-slope equation:

y + 4 = -1(x + 4)

y = -x + 0

So, the equation for this line is y = -x.

Y=-1x
or
y=-1x + 0

Considering you already have the slope & a point you end up having

Y = mx + b

-4 which is your Y so

-4=mx + b

M is your slope so

-4=-1(x) + b

Your x is 4 so

-4= -1(4) + b

B is your y intercept but because -4 = -1 times 4 your b is zero

Sweaters cost $42 each .For every 5 sweaters You buy,You get 1 sweater free.How much will a total of sweaters cost ?
solniwko [45]

<u><em>Note: I think you may have unintentionally missed to mention the amount of total sweaters for which we have to measure the cost. So, after a little research, I was able to find the complete question. So, I will answer your question based on the following completing question. Anyways, it would clear your concept hopefully.</em></u>

Here is the complete question:

<em>Sweaters cost $42 each. For every 5 sweaters You buy,You get 1 sweater free. How much will a total of 30 sweaters cost?  </em>

Answer:

The cost of 30 sweaters = $1050

Step-by-step explanation:

What to determine?

How much will a total of 30 sweaters cost?

Information Fetching and Solution Steps:

  • The cost of each sweater = <em>$42</em>
  • For every 5 sweaters You buy, you get 1 sweater free. It means you will be able to get 6 sweaters for the price of 5

As

The cost of 6 sweaters ⇒ The cost of 5 sweaters + 1 free = 42×5 = $210

So

If the cost of 6 sweaters = $210

Then

the cost of 30 sweaters = 210 × 5 = $1050

Therefore, the cost of 30 sweaters = $1050

What is the equation of the horizontal line that passes through the point (-2, -1)​
diamong [38]

Answer:

y= -1

Step-by-step explanation:

A horizontal line would mean that it has no slope, since the line is not decreasing or increasing. The horizontal line drawn through (0, -1) would pass through (-2, -1), since they share the same y coordinate.
