The sum or difference of vectors is simply the sum or difference of corresponding coordinates.
Answer:
points (x, y) = {(124, 68), (172, 80)}
y = 1/4x +37
Step-by-step explanation:
For the variable definitions given, the problem statement gives you the points ...
(chirps, temperature) = (x, y) = (124, 68) or (172, 80)
__
You are asked to find a linear equation that relates x and y.
The slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (80 -68)/(172 -124) = 12/48 = 1/4
The y-intercept can be found from ...
b = y -mx
b = 68 -(1/4)(124) = 37
Then the equation that models the relationship can be written ...
y = 1/4x +37

I think you meant to write 2* 69
X is confusing
But I think you meant multiplication problem so the answer is
2 times 69 = 138
