The equation of the line for given values is y = -5x - 7.
<h3>Given a point and a slope, how do you build an equation for a line?</h3>
When you know the slope of the line to be investigated and the provided point is also the y intercept, you may utilize the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.
The standard equation of straight line is y = mx + c.
Given m = -5 and y - intercept is -7
So, the equation of the line becomes y = -5x - 7

Answer:
The girth increases by 7 cm each year.
Step-by-step explanation:
Let y axis represents the girth in cm of the trunk of a fir tree and
x axis represents time in years.
Using the formula for slope : For any two points (x1 , y1) and (x2 , y2) the slope of the line(m) is given by:
m=y2-y1/x2-x1
From the graph:
Take any two points to find the slope of the line:
Let two points be (0, 5) and (5, 40)
Then, by the formula of slope:
m = 40-5/5-0 = 35/5 = 7
Therefore the answer is
The girth increases by 7 cm each year.

Answer:
29/35
Step-by-step explanation:
We need to get a common denominator of 35
3/7 *5/5 = 15/35
2/5 * 7/7 = 14/35
15/35+14/35 = 29/35
1. 45/6 = 7.5
7.5*10 = 75
So the penguin walks 75 ft in 45 seconds.
2. 45/10 = 4.5
4.5*6 = 27
The penguin takes 27 seconds to walk 45 ft.
