Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, -1). Use the box provided to submit all of your calculations and final answers. -
Please explain as thoroughly as you can! I'm reallly bad at math, any help is extremely appreciated! :D

y + 1 = (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Calculate m using the slope formula

m =

with (x₁, y₁ ) =(- 2, - 1) and (x₂, y₂ ) = (2, 1) ← 2 points on the line

m = = =

with point on line (x₁, y₁ ) = (- 2, - 1 ), then

y - (- 1) = (x - (- 2) ), that is

y + 1 = (x + 2) ← equation of line

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
