A) y = 5.044x + 56.113
C) y = -56.113x - 5.044
B) y = 56.113x - 5.044
D) y = -5.044x + 56.113
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! It is A.
One can get an idea of the intercept since y is large and doesn't get much smaller near 0, so the y-intercept is likely 56.113
Looking at the y values as a function of x, they tend to be larger, so the slope is likely positive. Both of those mean the first choice.
