Answer:
7/4 or 1.75
Step-by-step explanation:
Assuming this is a linear function, you can use the slope formula of change in y-values divided by change in x-values. Take your y-values (8 - 1), which is seven. Then take your x-values (6-2), which is equal to 4. Then your slope is just 7/4 or 1.75.
Y=5x-3
the slope is plus 5
so if 1 = 2
simply subtract 5 from two and you get -3
Answer:
8.9
Step-by-step explanation:
We know that 81 = 9², so √80 will be slightly less than 9. We can get a pretty good estimate by averaging 9 with 80/9. That result is 8.94, so about 8.9.
The attached graph shows that point on a number line.
Answer:
C
Step-by-step explanation:
Only the x values are affected.
So you add 5 to each of the x values.
0+5 = 5
-3+5 = 2
The points then become (5, - 5) and (2,-7)
The answer is C
