Write an equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis. Is the answer y=2x+3 ??

y = -1/2x + 9

Step-by-step explanation:

y - 7 = -1/2(x - 4)

y - 7 = -1/2x + 2

y = -1/2x + 2 + 7

y = -1/2x + 9

how is that middle school

step-by-step explanation:

< 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
