The slope-intercept equation for a straight line as - 3 x + 10.
Slope refers to a number that describes both the direction and the steepness of the line.
The slope-intercept equation for a straight line is given by:
y = m x + b;
where m = the slope and b = the y-intercept.
Here, we are given that:
m = slope = -3
y- intercept = b = 10
Put it in the equation y = m x + b, we get that:
y = (-3) x + 10
y = -3 x + 10.
Therefore, we get the slope-intercept equation for a straight line as - 3 x + 10.

8/1 bec ause 40 divided by 5 = 8 and 5 divided by 5 = 1
Answer:
The length of the shadow is decreasing 8 metres per second.
Step-by-step explanation:
In the attached figure, we draw the situation of the bear approaching the tree.
We can use the Tales to make some calculations.
The proportion between the height of the bear (h) and his shadow (S) is equal to the proportion between the height of the flashlight (H) and the sum of the distance of the bear (d) and the bear shadow.
This can be written as:
If we clear S we have:
We know that the distance is a function of time and it is reduced, as the bear approaches the tree, as a rate of 6 m/s.
We can express then the rate of variation of the shadow S as:
The length of the shadow is decreasing 8 metres per second.
If you were to use all 200, you could get 2 hours and 21 minutes. But if you were only using their base prices, you could get 1 hour and a half for $149.
Answer:
25
Step-by-step explanation:
You must divide 75/3. This is because for every 3 hours, there is a distace of 75 miles. You have to find out his average speed by finding his distance each hour. 75/3 is 25.
