Answer:
Step-by-step explanation:
The average is 7.5 hours of sleep each night.
There are 365 nights in 1 year.
Answer:
y = 2x - 6
Step-by-step explanation:
The slope-intercept equation is y = mx + b
where m is the slope and b is the point on the y axis when x=0 which is called the y intercept.
The slope is the rise over run.
Rise is the difference in the y values.
Run is the difference in the x values.
Rise = difference between -6 and -10 which is 4 units
Run = difference between 0 and -2 which is 2 units.
The slope would then be 4 over 2 or 4/2 which can be reduced down to 2.
If you visualize the line on the graph, the line slopes upward from left to right. So the slope must be a positive number.
Slope = 2
The y intercept is when x=0. One of the coordinates (0, -6) gives you that answer. When x=0, y = - 6. This is b.
Your equation would be y = 2x - 6
The answer is -60.
Why is this so??
The information we have here is that Rafeal rode his bike downhill by 6 kilometers.
Every kilometer he rides his bike, the altitude declines by 10m (meters)
let <em>m</em> represent how many meters the altitude declined.
If there is a positive number (ex. 2) multiplied by a negative number (-2), The result will be negative (-4) and vice-versa.
Same goes with division. positive number (4) divided by negative number (-2), the result will be a negative quotient.
<em>Therefore, the answer would be -60m, or -60 meters.</em>
