Answer:
The first one. Brainly is also in spanish
slope = (y2-y1)/(x2-x1)
= (70-52)/(8-1)
= 18/7
=2.6
point slope form
y-y1 = m(x-x1)
y-52 = 2.6(x-1)
distribute
y-52 = 2.6x-2.6
add 52 to each side
y = 2.6x+49.4
y = 2.6x +49
the initial temperature is 49.4 or about 49
and it increases about 2.6 degrees each week
The answer would be 3n - 8
Answer:
y= -a/bx +c/b
m= -a/b
b= c/b

Answer:
DE = 7.07 RS = 11.04 not congruent
Step-by-step explanation:
Formula:

D (5,0) E (0,-5)
DE




d= 7.07
R (-5,-5) S (6,-6)
RS




d= 11.04
