write in slope intercept form an equation of the line that passes through the given points (-2,3) (2,7)

1. Slope = Yb - Ya / Xb - Xa
= 7-3/2-(-2)
= 7-3/2+2
= 4/4
= 1

2. Y-intercept
Y = mx + b
7 = (1)(2) + b
7 = 2 + b
7 - 2 = 2-2 + b (two’s cancel out and we are just left with our b on the right side)
5 = B

Therefore, the equation is: Y = 1x + 5 which is also the same thing as: Y= X +5.

Someone please help??

Answer:

see below

Step-by-step explanation:

The problem statement seems to presume you have seen an exponential function like this written as ...

f(t) = a0·(1 +r)^t

where a0 is the value corresponding to f(0) and "r" is the fractional rate at which the value increases for each increment of t.

Here, 1+r corresponds to 1.04 in the given function, so r = 0.04 = 4%. When the value is greater than 0, it means there is an increase by that fraction each time t increases by 1.

Here, t is not defined, either, but it would usually be used to represent years in a situation like this. (In other situations, it might represent months, hours, or millenia.)

Hence, the appropriate choice is the one that describes a 4% annual increase.
