y+4 =1/2 (x+2)

now the standard form 2y+8=x+2
so -x+2y=-6 is the equation for line p in standard form

Verify seca(1-sina)(seca+tana)=1
beks73 [17]
Seca(1-sina)(seca+tana)=1
Left hand side
=(1-sina) (seca +tana) / cosa
=seca +tana - sinaseca - sinatan / cosa
=seca + tana -tana -(sin^2a/cosa) / cosa
=(1/cosa - sin^2a/cosa) / cosa
= (1-sin^2a / cosa) / cosa
= (1-sin^2a)/ (cos^2a)
=1 (verified)

Express 19.79 as a mixed number.
sergey [27]
Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator = 19.79 × 10 × 10 = 1979

Denominator  = 1 × 10 × 10 = 100

Numerator / Denominator = 1979 / 100

Simplifying our fraction

= 1979/100

= 1979/100

= 19  79/100
