Value of r is -4

Step-by-step explanation:

We are given points (-1,-6) and (0,r) on line and slope of line is -2. We need to find value of r.

Using slope formula when two points are given:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

Where $x_1=-1,\,\,y_1=-6,\,\,x_2=0,\,\,y_2=r$

Putting values:

$2=\frac{r-(-6)}{0-(-1)} \\2=\frac{r+6}{0+1} \\2=\frac{r+6}{1} \\2=r+6$

Adding -6 on both sides:

$2-6=r\\-4=r$

So, Value of r is -4

Simplify 2x^2+6x-7x+8-3x^2+1

Doss [256]

$(((((2*(x^2))+6x)-7x)+8)-3x^2)+1 \\ \\ ((((2x^2 + 6x) - 7x) + 8) - 3x^2) + 1 \\ \\ we \ would \ then \ (pull \ out) \ like \ terms. \\ \\ -x^2 - x + 9 = -1 * (x^2 + x - 9) \\ \\ \left[\begin{array}{ccc} -9 + 1 = -8 \\
 -3 + 3 = 0 \\
 -1 + 9 = 8 \\
\end{array}\right] \\ \\ Your \ answer: \boxed{\boxed{\bf{ -x^2 - x + 9
}}}$

I hope this helps you!
