1. y = 1/3x - 6

2. (from top to bottom) right, right, wrong, wrong, right

Hi There!

Question 1:

y = 1/3x - 6

Question 2:

y = -1/2x + 2

-1/2 or 1/2 = slope

2 = y intercept

Answers:

The graph is a straight line.

The slope of the line is 1/2.

The y intercept is 2.

Hope THis Helps :)

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
