Line n passes through the points (-3,-7.5) and (2,-5). Thalia determined that the equation of the line n is y=0.5x. Explain the

yKpoI14uk [10]

<h3>The error is -6 </h3>

Step-by-step explanation:

If a line passes through the points $(x_1,y_1)$ and $(x_2,y_2)$

Then the equation of line is

$\frac{x- x_1}{x_1-x_2} =\frac{y-y_1}{y_1-y_2}$

Here given points are (-3,-7.5) and (2,-5)

Then the equation of the line is

$\frac{x+3}{-3-2} =\frac{y+7.5}{-7.5+5}$

⇔ $\frac{x+3}{-5} =\frac{y+7.5}{-2.5}$

⇔2.5(x+3) = 5(y+7.5)

⇔(x+3)= 2(y+7.5)

⇔x+ 3 = 2y +15

⇔2y = x+3-15

⇔y = $\frac{x-12}{2}$

⇔y = 0.5 x -6

The error is -6

Two consecutive integers whose product is 56

Iteru [2.4K]

<u><em>≡ We know that:</em></u>
⇔ Consider the first integer is $a$
⇔ So, the next integer is $(a+1)$

<u><em>≡ Solution:</em></u>
⇒ $(a).(a+1)=56$
⇒ $a^{2}+a=56$
⇒ $a^{2}+a-56=0$
⇒ $(a+8)(a-7)=0$
⇒ $a_{1}=-8$ ║ $a_{2}=7$

⇔ For $a=-8$
⇒ the next integer is $(a+1)=-8+1=-7$

⇔ For $a=7$
⇒ the next integer is $(a+1)=(7+1)=8$

<em>∴ So, there are 2 options</em> [ $\boxed{-8}$ <em>and</em> $\boxed{-7}$ ] <em>or</em> [ $\boxed{7}$ <em>and</em> $\boxed{8}$ ]
