Answer:

x = -2      <u><em>OR</em></u>     x = -3

Step-by-step explanation:

=> x^2+5x+6 = 0

Using mid-term break formula

=> x^2+2x+3x+6 = 0

=> x(x+2)+3(x+2) = 0

Taking x+2 common

=> (x+2)(x+3) = 0

So Either,

x+2 = 0   <u><em>OR</em></u>    x+3 = 0

x = -2      <u><em>OR</em></u>     x = -3

Equation:

y - 10 = -5x

Solve:

(y - 10) + 10 = (-5x) + 10

y = -5x + 10

Remember the formula (Slope Intercept Form):

y = mx + b

m = Slope (Rise/Run)

b = Y-intercept

So your graph would look something like the attached image:
