Recall that slope intercept form is written exactly the way it's described: it gives you the slope of the line, then its y-intercept.

So first we can look at the graph, and see that for every 1 unit traveled to the right, the line travels 3 units down.  Therefore our slope is -3.

Now we look for the y-intercept - we see the line intersects the y-axis at -3.

So our equation is:

y = -3x - 3

A snail moved 5 feet in 2 hours. How many feet will the snail move in 5 hours?
mamaluj [8]
The best way to do this is to set up a proportion

2       5
--- = ----
5       x

then cross multiply and divide

5 times 5=25/2=12.5

he would move 12.5 feet in 5 hours

I hope I've helped!

-x+y=15−x+y=15 and -5x-3y=27−5x−3y=27 <br> Solve the system of equations by combining the equations
Arisa [49]

Answer:

x = -9, y = 6.

Step-by-step explanation:

-x + y = 15

-5x - 3y = 27

From the first equation:

y = x + 15.

Substituting for y in second equation:

-5x - 3(x + 15) = 27

-8x - 45 = 27

-8x = 72

x = -9.

Now plug x = -9 into equation 1

-(-9) + y = 15

y = 15 -9 = 6.

A nursery owner buys 9 panes of glass to fix some damage to her greenhouse. The 9 panes cost
Nadya [2.5K]

Answer: $11.80 for another 4 panes of glass.

Step-by-step explanation: We know that 9 panes of glass cost $26.55, but we should first find how many dollars would it cost per pane of glass, or 1.

So, we can divide 26.55 by 9 to find the price per 1 pan of glass.

26.55/9 = 2.95, or $2.95 per pane of glass.

Now, we want to know how much it will cost for 4 panes of glass. Simply multiply 2.95 by 4.

2.95 x 4 = 11.8, or $11.80 for another 4 panes of glass.

mafiozo [28]

Answer:

A. 4

Step-by-step explanation:

Constant of proportionality (k) = y/x

We can use the coordinates of any point on the line to find k.

Let's use (2, 8)

Constant of proportionality (k) = 8/2

Constant of proportionality (k) = 4
