I think it is 3 good luck me saying this then u getting the wrong answer
The slope (increase) is 0.26 and the y-intercept (start) is 67.6.
You could describe the temperature outside using this equation.
For example, at the beginning of the day, the temperature was 67.6. Then, it increase by 0.26 degree for every given amount of time (minutes or hours).
1-4 are not there but here it is without them
The slope would be -1 because of the x
