-3/2

Step-by-step explanation:

The slope is the ratio of rise to run, the change in y divided by the change in x. It is often designated by the letter "m".

m = (change in y)/(change in x) = (-7 -(-1))/(5 -1) = -6/4

m = -3/2

The slope of the line through the given points is -3/2.

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ -1}})\quad 
% (c,d)
&({{ 5}}\quad ,&{{ -7}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-7-(-1)}{5-1}\implies \cfrac{-7+1}{5-1}
\\\\\\
\cfrac{-6}{4}\implies -\cfrac{3}{2}$

-3/2

Step-by-step explanation:

the formula for slope is y1-y2/x1-x2

where

y1 is the first point's y coordinate

x1 is the first point's x coordinate

y2 is the second point's y coordinate

x2 is the second point's y coordinate

so now we can plug our points in

-1-(-7)/1-5

6/-4

simplify

-3/2

A 4300-N force from a car s engines produces an acceleration of 3.3 m/s2. What is the mass of the car? A. 4300 kg B. 1300 kg C. 14,000 kg D. 390 kg

Step-by-step answer

P Answered by PhD

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

=4300/3.3

=1303.03kg

History

In 1760, following the signing the Treaty of Paris, virtually all of North America that had been French, was suddenly British. The might have been the beginning of long standing British control over a vast empire based on raw materials, agriculture and manufacturing connected by unfettered Atlantic trade. Yet in less than a decade revolution was in in the air. Discuss slavery, the Seven Years War, Pontiac's War, and anything else from this period of time, that may explain the conditions that led to the beginning of the American Revolution.
