Which of the following lines is parallel to the line 4x+y=5? y=4x - 2
y=-4x +9
y= 1/4x+8
y=-1/4x - 1

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

i those same problems in math and dont know how to do them

114 plus 113 times 2 and 114 times 3

depends what are you allowed to do ?
