Answer:
.55
Step-by-step explanation:
You want to shorten the decimal to just to two after the decimal point. If so for example, .443 would be shortened to .44, but if the third number is 5 and up, you would take the second number after the decimal point and add 1. For example,
.446 would round up to .44, which is why .5524 would round to .55
With this problem you just look at the graph and answer it that way. Look at where the heart rate is at its max and then look at the beginning and end, the shape of the graph. Then answer the question.
The correct answer would be #3
The slope-intercept form: y = mx + b
We have the slope m = 9, therefore: y = 9x + b.
Next. We have the table:
x | -5 | -2 | 1 | 3 | 4 |
y |-46|-19| 8 |26|35|
(1, 8) → x = 1, y = 8
substitute the values of x and y to the equation:
8 = 9(1) + b
8 = 9 + b |-9
b = -1
Answer: y = 9x - 1 → y-intercept is -1.
