Question

Find the equation of the linear relationship

Answer 1

answer is 10---- i think

Answer 2

Answer:

y = -2x + 170

Step-by-step explanation:

(30, 110)    (40, 90)                          y = mx + b

x1      y1     x2    y2                         90 = -2 (40) + b

90  -  110 =   -20   =  -2                 90 = -80 + b

40  -  30        10                           +80   +80

                                                     170 = b

really hope this helps :)
