Answer:
miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.
Step-by-step explanation:
As there is no graph mentioned here but the information are quite sufficient to answer the question.
We have points
From these points we can find the slope of the line .
From point slope formula
And assigning and
This slope is also the speed of the bird which is
As by plugging the values of any coordinate point we can confirm this.
Lets put , y-axis is the distance so in
minutes the the distance covered by the bird must be equal to to y-axis value which is
miles.
Now as in the bird has started from y-intercept value
so we can say that,the original distance of the bird from its nest is
.
So the correct choices are: and
The birds speed is per minute and is
away from its nest.
Answer:
An equation in point-slope form of the line that passes through (-4,1) and (4,3) will be:
Step-by-step explanation:
Given the points
- (-4,1)
- (4,3)
Finding the slope between the points (-4,1) and (4,3)
Refine
Point slope form:
where
- m is the slope of the line
- (x₁, y₁) is the point
in our case,
- m = 1/4
- (x₁, y₁) = (-4,1)
substituting the values m = 1/4 and the point (-4,1) in the point slope form of line equation.
Thus, an equation in point-slope form of the line that passes through (-4,1) and (4,3) will be:
