The slope of the line is -\frac{2}{3}, and any line that is parallel to a line that has a slope of -\frac{2}{3} always has the same slope because lines that are parallel always have the same slope.

\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{0}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-2}{3-0}\implies -\cfrac{2}{3}

Can anyone explain slope and point-slope to me?
son4ous [18]
Slope is a constant rate of change; change in y over change in x; rise over run; represented by the variable m. Point slope is the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line.

For what value of a does (1/9)^a+1 =81^a+1 x 27^2-a ?<br><br>-4<br>-2<br>2<br>6
EastWind [94]

Answer:

- 4

Step-by-step explanation:

Using the rule of exponents

• a^{m} × a^{n} ⇔ a^{(m+n)}

• a^{-m} ⇔ \frac{1}{a^{m} }

(\frac{1}{9}) ^{a+1} = 9^{-(a+1)} = 3^{-2(a+1)}

and right side

= 3^{4(a+1)} × 3^{3(2-a)}

Hence

3^{-2a-2} = 3^{4a+4} × 3^{6-3a}

3^{-2a-2} = 3^{a+10}

Equating exponents on both sides gives

a + 10 = - 2a - 2 ( add 2a to both sides )

3a + 10 = - 2 (subtract 10 from both sides )

3a = - 12 ( divide both sides by 3 )

a = - 4

a triangle= 180º total

a right triangle has one 90º angle

there is a 30º angle given

180-90=90
