Mx + b from

2y - 6x = 12

  3x + 6

the slope, m, is 3

the y-intercept, b, is 6

Step-by-step explanation:

Change to slope intercept form, y = mx + b

First, isolate y on the left

2y -6x = 12  Add 6x to both sides  (6x cancels on the left)

2y/2 = 6x/2 + 12/2  Divide both sides by 2  (2 cancels on he left)

y = 3x + 6

the slope, m, is 3

the y-intercept, b, is 6

step-by-step explanation:

$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
