Graph the ordered pair (-4,-1)

Go to the x-axis (horizontal part) and find -4 on your graph. Then go down on the y-axis (vertical part) and look for -1. That's where you're going to plot the point, (-4, -1). I attached a photo to give you a visual.

step-by-step explanation:

my gg bhitch

< 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
