Answer:
(x+1)(x-5)
Step-by-step explanation:
(x+a)(x+b)=x²-4x-5
then a+b=-4 and a*b=-5
so a=-1 and b=5
Answer:
y-8=2(x+2)
Step-by-step explanation:
Equation of a line is easy once you get the hang of it. State with the point slope form y-y2=m(x-x2) Simply plug in the points given to get the equation.
Answer:
y = -x + 10
Step-by-step explanation:
Slope Formula:
Slope-Intercept Form: y = mx + b
Step 1: Find slope <em>m</em>
m = (11 - 9)/(-1 - 1)
m = 2/-2
m = -1
y = -x + b
Step 2: Find y-intercept <em>b</em>
9 = -(1) + b
9 = -1 + b
b = 10
Step 3: Rewrite linear equation
y = -x + 10
