(x+2)(x-1)= x^2+2x-x-2= x^2 +x -2\\\\( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 =x^2+x-2-x^2+1=x-1\\\\- 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] =-3(x-1)=-3x+3\\\\- 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] + 3 ( x - 1 ) =-3x+3+3x-3=6x\\

How do u find the slope of (6,-10), (-15,15)
Sergeu [11.5K]
m = \frac{y_{2} - y_{1}}{x_{2}-  x_{1}} = \frac{15 - (-10)}{-15 - 6} = \frac{15 + 10}{-21} = \frac{25}{-21} = -1\frac{4}{21}

     y - y₁ = m(x - x₁)
y - (-10) = -1⁴/₂₁(x - 6)
   y + 10 = -1⁴/₂₁(x) + 1⁴/₂₁(6)
   y + 10 = -1⁴/₂₁x + 7¹/₇
       - 10              - 10
           y = -1⁴/₂₁x - 3¹/₇
