Given an equation of a line to represent the association between latitude and temperature as
y = -1.07x + 1119
Answer:
The answer is 64.
Step-by-step explanation:
Lets say the top row is <em>x</em> and the bottom row is <em>y</em>.
Since when <em>x</em> is 13 <em>y</em> is 104 and when <em>x</em> is 14 <em>y</em> is 112 that means the <em>y </em>value goes up by 8 every time.
when x=3: 16+8=24
when x=4: 24+8=32
when x=5: 32+8=40
when x=6: 40+8=48
when x=7: 48+8=56
when x=8: 56+8=64
Hope this helps you!!!!
