Line p contains points a(-1,4) and b(3,-5) lines q is parallel to line p. line r is perpendicular to line q. what is the slip of line r

The slope of line r is

Step-by-step explanation:

Given as :

The points that line p contains is A ( - 1 , 4 )  and  B ( 3 , - 5 )

Let The slope of line p =

So,   =

Or , =

Or, =

Now, Again ,

Line q is parallel to the line p

let The slope of line q  =  

So, for parallel lines

slope of lines are equal

I.e   =

∴  =

Again ,

Line r is perpendicular to the line q

let The slope of line r  =  

So, for perpendicular lines

The product of the slopes of two line = - 1

× = - 1

or, ×    = - 1

or,    =

∴   =  

So, The slope of line r =   =  

Hence , The slope of line r is  . Answer

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
