A line contains (82,-96) and (87,-86) what is the slope of the line in simplified form

TiliK225 [7]

Here the change in x is +5 and that in y is +10 (from y= -96 to y= -86). Thus, the slope, (change in y) / (change in x) is m = 10/5, or m = 2.

Which expression is equivalent to StartFraction (3 m Superscript negative 1 Baseline n squared) Superscript negative 4 Baseline

koban [17]

Answer:

$3m^{10}n^{-11}$

Step-by-step explanation:

Given the expression $\frac{(3m^{-1}n^{2})^{-4} }{(2m^{-2}n)^{3} }$ , we will use laws of indices to get the equivalent expression as shown below;

According to one of the law of indices,

$\frac{a^{m} }{a^{n} } = a^{m-n} \ and\ (a^{m})^{n} = a^{mn}$

$\frac{(3m^{-1}n^{2})^{-4} }{(2m^{-2}n)^{3} }\\= \frac{3m^{4}n^{-8} }{2m^{-6}n^{3} }\\= 3m^{(4-(-6))} * n^{-8-3}\\ = 3m^{10}n^{-11}$

This gives the required expression

Which point-slope equation represents a line that passes through (3, –2) with a slope of -4/5?

alexira [117]

Answer:

$y+2=-\frac{4}{5}(x-3)$

C is correct equation.

Step-by-step explanation:

We are given a point and slope of a line. Using point slope form formula to find the equation of line and match the correct option.

Formula:

$y-y_1=m(x-x_1)$

where,

$slope (m)=-\frac{4}{5}$

$Point:(x_1,y_1)\rightarrow (3,-2)$

Equation of line:

$y-(-2)=-\frac{4}{5}(x-3)$

$y+2=-\frac{4}{5}(x-3)$

Thus, C is correct equation of given information.
