Answer:
A
Step-by-step explanation:
the formula of the slope is (y2 - y1)/(x2 - x1)
slope = (3-2)/(-1-2) = 1/(-3) = -1/3
Answer:
D)graph c
Step-by-step explanation:
it's my opinion do not take it as important
Move the decimal 2 places to the right resulting in the answer 2,380
10% of 80 = 8
80 - 8 = 72
if they are 10% off, the contact lenses will cost $72
The answer is A. Slope is rise/run. According to the graph, you can trace out and see that it rises 1 and goes to the right 4 times. This means that it has a positive slope of 1/4. And the line crosses the y intercept at y = 3
So answer choice A is correct.
