Answer:
-2
Step-by-step explanation:
you have to rearange in the form of
y=mx+b, where m is the slope
y -6= -2( x-8)
y = 6 -2x + 16
y= -2x +22
slope is -2
Using the slope-intercept form, the slope is −2 .
The Answer is D
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
it would be 32
you would add them all up then divide it by five
2.4 hours
