A line passes through the points (6,-6) and (9,-5). What is it’s equation in point slope form?

BARSIC [14]

Answer:

$y=\frac{1}{3}x-8$

Step-by-step explanation:

Slope-intercept form of an equation is written as $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept.

The slope of a line that passes through the points $(x_1,\: y_1)$ and $(x_2, \: y_2)$ is $m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$ . Using the coordinates $(6,-6)$ and $(9,-5)$ as given in the problem, we have slope of this line to be:

$m=\frac{-5-(-6)}{9-6}=\frac{1}{3}$ .

Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:

$-6=\frac{1}{3}(6)+b, \\ b=-8$

Therefore, the equation of this line in slope-intercept form is $\fbox{$y=\frac{1}{3}x-8$}$ .

Reed wants to buy a new tent for an upcoming camping trip. The tent is marked down from its original price by 20%, and Reed has

lukranit [14]

You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.
