Answer:
Step-by-step explanation:I
The line in the option C is the best model for the data in the scatter plot. Since in this scatter plot the points above and below the line are equally distributed (i.e. there are 5 points above the line and 5 points below the line) whereas in the rest three graphs the distortion above and below the graph is unequal.
2/9 of 50 = 11.1
Ethan spends 11.1 hours feeding the animals every week
It can be either B. 11 or C. -11
We can just substitute y = 4x+1 in the second equation.

We know the value of x, substitute x in any equations to get the y-value.

The value of y is 3 and the value of x is 0.5 aka 1/2
Since you want the solution as a point then It's below here.
Two angles are supplementary if their measures sum 180°.
Linear angle pairs are adjacent angles (they are together) and they form a straight angle, which is 180°. Therefore, they are supplementary.
But two angles may be separated and yet add 180°, then they are supplementary but are not linear angle pairs.
