Which shows this the equation in slope-intercept form? y=-4/7x+9

This does show the equation in slope-intercept form

Step-by-step explanation:

Slope intercept form is written as:

y = mx + b

In which, the m is slope and b is the intercept. In this case the slope would be -4/7 and the intercept would be 9.

< 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
