What is the slope and y-intercept of this line y= -2x+8

a. slope: 8 y-intercept: -2

b. slope: 2 y-intercept: -8

c. slope: -1 y-intercept: 4

d. slope: -2 y-intercept: 8

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

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
