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$}$ .

Darlene's dog weighed 5 times as much as Leah's Dog.Together,the dogs weighed 84 pounds. How much did each dog weigh?Write an eq

Triss [41]

Let d = Darlene's dog's weight
let l = Leah's dog's weight
d = 5l
d + l = 84
so, 5l + l = 84, which means 6l= 84
so, l = 84/6 = 14d = 5(14) = 70
<span>Darlene's dog = 70 lbs, Leah's dog = 14 lbs</span>
