Pie

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

$y = mx + b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

$(0, -4)\\(1,0)$

We found the slope:

$m = \frac {y2-y1} {x2-x1}\\m = \frac {0 - (- 4)} {1-0} = \frac {4} {1} = 4$

So, the equation is of the form:

$y = 4x + b$

We substitute a point to find "b":

$-4 = 4 (0) + b\\-4 = b$

Finally, the equation is:

$y = 4x-4$

By multiplying integers what is the total of (-10)(0)

34kurt

Anything multiplied by 0 is zero. 100000 * 0 = 0, -1000 * 0 = 0.

Therefore, (-10)(0) = 0.

An older toilet uses 27 l per flush, whereas a replacement toilet uses only 6 l per flush. if you flush the toilet four times pe

ipn [44]

Find out how many liters are used in the old toilet in a year;

4×27= 108 l (in a day)
365×108= 39420 liters (in a year)

Find out how many liters are used in the new toilet;

4×6=24 (in a day)
24×365=8760 l (in a year)

Find the water saved; 39420-8760
= 30660 l saved.

Hope I helped :)
