The slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

This is the formula we have so far:

y = -9x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(-4, -2)

-2 = -9(-4) + b

-2 = 36 + b

-38 = b

y = -9x - 38

Hope this helped!

Answer:

y=-9x-38

Step-by-step explanation:

In slope intercept form we know that the equation for a line is given by

y=mx+b, Where m is the slope (which we have and is -9) and b is the 'y' axis intercept point.

Lets use the given point (-4,-2) to find b

y=-2 and x=-4

-2=-9*-4 +b

We have b=-38

three friends earned more than $200 washing cars. they paid there parents $28 for supplies and divided the rest of money equally
makvit [3.9K]
So
x=earned
x>200
they paid their parrents 28 for supplies (this assumes that they paied 28 altogether and not 28 each)
so subtract 28 from pay
new pay=y
y>200-28
y>172
divided it among themselves (3)
172/3=57 and 1/3=57.33
they each earned more that $57.33

Make a table for the following equations<br> y = 2x + 4
nekit [7.7K]

In order to make a table, we sample some x values (whichever we want), and we compute the expression for those value. Each x value will yield a unique y value.

If you need this table to graph the function, you'll only need two points, since this is a line, and having two points you just need to connect them.

Here are some samples, feel free to make more if you need to:

f(x)=2x+4\implies f(0)=2\cdot 0 + 4 = 4

f(x)=2x+4\implies f(1)=2\cdot 1 + 4 = 6

f(x)=2x+4\implies f(2)=2\cdot 2 + 4 = 8

f(x)=2x+4\implies f(3)=2\cdot 3 + 4 = 10

f(x)=2x+4\implies f(4)=2\cdot 4 + 4 = 12

So, we have the following table

\begin{array}{c|c}0&4\\1&6\\2&8\\3&10\\4&12\end{array}
