The equation of the line thru <span> (14,5) and (19,15)  is found as follows:

                      15-5           5
slope = m = ----------- = ------ = -1
                       19-14         5

Thus, the slope of any line perpendicular to this first line has the slope

m = -1/1 = -1.

Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>

kolezko [41]

Answer:

1. Alissa can conclude that there are fewer students at her school that want to visit Japan (7) than Australia (13)

Pets that don't have a home is more than the pets that have a home

The statement is not misleading

How is multiplying rational numbers like multiplying integers
Anna [14]

Hello from MrBillDoesMath!

Answer:

See Discussion below

Discussion:

Let  a/b and c/d be rational numbers we wish to multiply. Then

(a/b) * (c/d) = (a*c)/(b*d)


The numerator (a*c) is the product of two integers ( a and c) and the  denominator (b*d) is also ( b and d). In that way  multiplying rational numbers is like multiplying integers.


Thank you,

MrB
