How can -6.75 + (10.25) be expressed as the sum of its integer and decimal parts

 -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Here, the integer part  =     ( (-6)  + (10))

Decimal part =   ( (-0.75) + (0.25))

Step-by-step explanation:

Here, the given expression is:    -6.75 + (10.25)

Now, -6.75  = (-6)  +  (-0.75)

Also, (10.25)  = (10)  + (0.25)

So, the expression can be written as

 -6.75 + (10.25)  =  (-6)  +  (-0.75) +  (10)  + (0.25)

                           = ( (-6)  + (10))  + ( (-0.75) + (0.25))

or,   -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Where the integer part is    ( (-6)  + (10))

and the decimal part is  ( (-0.75) + (0.25))

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
