Exact Form: -245/12 , Decimal Form: -20.4166666, or Mixed Number Form: -20 5/12
Answer:
y =
x - 5
Step-by-step explanation:
Given f(0) = - 5 and f(4) = - 3 , then we have the coordinate points
(0, - 5) and (4, - 3)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 5) and (x₂, y₂ ) = (4, - 3)
m =
=
= 
The line crosses the y- axis at (0, - 5) ⇒ c = - 5
y = f(x) =
x - 5 ← equation of line
x+y = -19
x*y = 35
x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437
