(-5,2) (-5,-1) how to find the slope-intercert form

Novay_Z [31]

The slope-intercept form of (-5,2) (-5,-1) is undefined

Solution:

Need to find the slope intercept form of line passing through two point (-5,2) (-5,-1).

Slope intercept form of line passing through $\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right)$ is given by

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\left(x-x_{1}\right)$

$\text { Here in this problem } \mathrm{x}_{1}=-5, \mathrm{x}_{2}=-5, \mathrm{y}_{1}=2 \text { and } \mathrm{y}_{2}=-1$

On Substituting the values we get the slope intercept form of given points,

$\begin{array}{l}{y-2=\frac{-3}{0}(x+5)} \\\\ {y-2=-\frac{3(x+5)}{0}}\end{array}$

= undefined

Hence the slope intercept form of given points is undefined

The points (-6, r) and (6,3) lie on a line with slope 3/4. Find the missing coordinate r.

iren [92.7K]

Answer:

r=-6

Step-by-step explanation:

$m=\frac{y2-y1}{x2-x1} \\\frac{3-r}{6-(-6)} =\frac{3}{4} \\4(3-r)=3(12)\\12-4r=36\\-4r=24\\r=-6$

At the beginning of an environmental study, a forest covered an area of 1500 km2 . Since then, this area has decreased by 9.8% e

fredd [130]

Answer:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$

Step-by-step explanation:

In this problem, the initial area of the forest at time t = 0 is

$A_0 = 1500 km^2$

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.

So for instance, after 1 year, the area is

$A_1 = A_0 \cdot \frac{90.2}{100}=0.902 A_0$

After 2 years,

$A_2=0.902 A_1 = 0.902(0.902A_0)=(0.902)^2 A_0$

And so on. So, after t years, the area of the forest will be

$A(t)=(0.902)^t A_0$

And by substituting the value of A0, we can find an explicit expression:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$
