Cada par de puntos determina una recta con la pendiente dada. Halla el valor de la incógnita en cada caso: a. (3,2);(4,x); m=1 b. (b,-1);(2,-2); m=-1/2 c. (5,d);(9,2); m=-3/4 d. (-1/3,3/4);(h,5/6); m=7/12

a=3,b=0,c=5,d=-4/21

Step-by-step explanation:

The formule we use to get the slope is:

m =

a. (3,2);(4,x); m=1

 → x= (1)(4-3)+2 → 3

b. (b,-1);(2,-2); m=-1/2

 → -1= ()(2-b) →   → 0

c. (5,d);(9,2); m=-3/4

 →  d= ()(9-5)-2 → 5

d. (-1/3,3/4);(h,5/6); m=7/12

  →  =   ()  →  

We get this equation with the original one:

y=mx+b

There are three  forms of linear equations:

point-slope form y2-y1=m(x2-x1)

standard form Ax + By + C = 0 or Ax + By = C

and slope-intercept form y=mx+b

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

$649.60
