Answer:
y-intercept (0, -47/8)
Step-by-step explanation:
Point slope equation form:
y + 7 = -1/8(x - 9)
y + 7 = -1/8 x + 9/8
y = -1/8 x + 9/8 - 56/8
y = -1/8 x - 47/8
y = mx + b where m=slope and b = y intercept
In this case, y intercept = -47/8
Answer:
y-intercept (0, -47/8)
65/100 or 13/20
Both work, it's just that 13/20 is simplified
Answer:
-4x-4
Step-by-step explanation:
(4x-4) can't be combined so they are not relevant. 4x-8x = -4x and -4 is unchanged.
Answer:
There is a positive correlation between the number of hours spent on homework and the test scores. So, the more homework you do, the better your test score.
Step-by-step explanation:
The data given is representative of a scatter plot, which shows a relationship with two sets of data that, when using a line of best fit, will show either a positive correlation (increasing), a negative correlation (decreasing) or no correlation (the data shows no overall pattern). In this case, you can see that the overall pattern of data is increasing, or a positive correlation. Which means that, in general, the more hours of homework you do, the more likely you are to receive a better test score.
Answer:
Step-by-step explanation:
y - 0 = 5/2(x + 2)
y = 5/2x + 5
