The two options you picked are indeed correct.
The measure of angle z is 137
Answer:

Step-by-step explanation:
To get d isolated we have to divide both sides by N to cancel the out the N on the side which d is on. Once we do that d is alone and on the other side we have c over n.
Answer: the slope intercept would be 2/9
Step-by-step explanation: first, plot the points on a graph, from the first point count up to the 10 line, that would be 2 (which is the rise), then from the point you’re at (which is (-8,10)) count across till you reach the other point (you would count 9, thats the run)
so the the answer is rise/run = 2/9
