Answer:
The answer is B. (y=16x)
Step-by-step explanation:
1 times 16 is 16. 2 times 16 is 32. 3 times 16 is 48. Its like a pattern
The equation of the line is y = -2x + 16 which passes through the point (4, 8) and has a slope of -2.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The line that passes through the point (4, 8) and has a slope of -2.
On comparing the standard equation:
y = mx + c
Here m is the slope of the line and c is the y-intercept.
m = -2
y = -2x + c
Plug x = 4 and y = 8
8 = -2(4) + c
c = 16
y = -2x + 16
Thus, the equation of the line is y = -2x + 16 which passes through the point (4, 8) and has a slope of -2.

Answer:
50.465 km
Step-by-step explanation:
In order to find the distance in kilometers, you need to first convert the marathon distance into yards. Since the conversion measurement of 1 mile = 1760 yards is given, you can use this to find the total yards in 26 miles:
or x = 45,760 yards
Adding this amount to the additional 385 in the marathon distance:
45760 + 385 = 46,145 yards
Since 1 yard = 0.9144 meters, we can find the number of meters the same way we found yards:
or m=50,465 meters
Since the question is asking for kilometers, we can need to divide the number of meters by 1000, or move the decimal point three places to the left:
50,465 ÷ 1000 = 50.465 km
