Find the slope of the line that passes through (10,8) and (8,0).​
N76 [4]

Answer:

The slope of the line that passes through points ( -10, -8 ) and ( -8, -16 ) is -4.

Explanation:

Points given = ( -10, -8) and ( -8, -16)

Slope = ?

( -10, -8 ) : x1 = -10 and y1 = -8

( -8, -16 ) : x2 = -8 and y2 = -16

We know,

slope = y2 - y1 / x2 - x1

Slope = -16 - ( -8) / -8 - (-10)

slope = -16 + 8 / -8 + 10

slope = -8 / 2

slope = -4

Therefore,  slope of the line that passes through points ( -10, -8 ) and ( -8, -16 ) is -4.

likoan [24]

Answer:

\boxed{66}

Step-by-step explanation:

if \: the \: question \: is \: f[g(4)] \\ then \: at \: first \: solve \: for \: g(4) \\ g(4) =  {4}^{2}  \\ f[g(4)]  = 4( {4}^{2} ) + 2 \\ f[g(4)]  = 4(16) + 2 \\ f[g(4)]  =64 + 2 \\   f[g(4)]  =  \boxed{66}
