What is an
equation of the line that passes through the points (-4, 2) and
(-8, -3)?

Step-by-step explanation:

The equation of a straight line can be written as .

With the pair of coordinates (coordinates are written in the form ) , the following can be written:

To solve for a variable, we can use elimination:

 (subtract the second equation from the first)

( is eliminated)

To solve for the other variable, we can use substitution:

is the linear equation for the line that passes through the points and

i think it is 70

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
