Answer:

The equation of line is shown below.

Step-by-step explanation:

The equation of line is

$y+1=\frac{-3}{5}(x-4)$

It is the point slope form of a line, therefore the slope of the line is $\frac{-3}{5}$ and the line passing through (4,-1).

Rewrite the above equation in slope intercept form.

$y=\frac{-3}{5}x+\frac{12}{5}-1$

$y=\frac{-3}{5}x+\frac{12-5}{5}$

$y=\frac{-3}{5}x+\frac{7}{5}$

The point slope form of a line is

$y=mx+b$

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

Therefore the slope of the line is $\frac{-3}{5}$ and the y-intercept of the line is $\frac{7}{5}$ .

Slope is defined as

$m=\frac{Rise}{Run}$

Since the slope is negative, therefore the run of the line is considered on the left side. The line rise by 3 and run by 5, therefore we will add 7 in y and subtract 5 from x.

The y-intercept is $(0,\frac{7}{5})$ .

$(0-5,\frac{7}{5}+3)=(-5,\frac{22}{5})=(-5,4.4)$

Therefore we have three points (4,-1), (-5,4.4) and (0,1.4). Plot the point on the coordinate plane and connect them be a straight line.

In a family’s monthly budget, 2/5 of the income is spend on housing and 1/5 of the income is spent on food. How would you determ

aniked [119]

Answer:

2/5 is left

Step-by-step explanation:

Add the two you have so far together. 2/5+1/5=3/5

So 3/5 of your budget is used. 3/5 is a fraction, meaning that 5 is the whole.

Subtract 3 from 5 and you get 2. There are 2/5 left in the budget for everything else.

You saw on the previous page that 2/11=0.18. Show how you can use what you know about the decimal for 2/11 to find the decimal f

pantera1 [17]

1/11 is half of 2/11. (1/11 + 1/11 = 2/11)

As 2/11 = 0.18, 1/11 must equal half of 0.18.

Half of 0.18 is 0.09. Thus the decimal for 1/11 is 0.09.
