Answer:
Step-by-step explanation:
The formula for point slope form is (y-y1) = m(x - x1)
In this formula m will always be the slope. So, you can substitute 3 in for m
(y-y1) = 3(x-x1)
y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.
(y - 1) = 3(x - (-2))
But since it is minus a negative it changes to a positive so it would be:
(y -1) = 3(x + 2)
Hope this helps!
Answer:
x = -2/3
Step-by-step explanation:
27 ^(x+2) = 81
Rewrite 27 as a power of 3
27 = 3^3
Rewrite 81 as a power of 3
3^4
3^3^(x+2) = 3^4
We know that a^b^c = a^(b*c)
3^3*(x+2) = 3^4
3^(3x+6) = 3^4
The bases are the same so the exponents are the same
3x+6 = 4
Subtract
6 from each side
3x+6-6 =4-6
3x = -2
Divide by 3
3x/3 =-2/3
x = -2/3
