If they give you a point and slope, use point slope form.
Then simplify to get slope intercept form (y = mx + b)
slope (m) = 5
(-2, 1)
y - y1 = m(x - x1)
y - 1 = 5(x + 2)
y - 1 = 5x + 10
y = 5x + 11
The extraneous solution is x=-1 and x=-6
Step-by-step explanation:
Given the question as;

Eliminate the root in the left hand side

solve the quadratic equation by factorization
Find multiples of 6 that add up to 7-------- 1*6
Rewrite the equation as;
x²+7x+6=0
x²+6x+x+6=0
x(x+6) +1 (x+6) =0
(x+1)(x+6) =0
x+1=0
x=-1
or
x+6=0
x=-6
The roots are, x=-1, and x=-6
