How do i simplify -5(x+9)=-5

Step-by-step explanation:

-5(x + 9 ) = -5

-5*x + (-5) * 9 = -5

-5x - 45 = -5           {Add 45 to both the sides}

-5x - 45 + 45 = - 5 +45

-5x + 0 = 40

-5x = 40      {Divide both sides by (-5)

-5x/-5 = 40/-5

x = -8

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

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

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
