Use the point-slope formula and the given points to chose the slope intercept form of the linear equation. (8, 5), (-4, -1) [use (8, 5) ] A. y= -2x + 1. B. y= 2x + 1. C. y = - 1/2x + 1. D. y= 1/2x + 1​

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
