Answer:
Equation of the line:
.
Step-by-step explanation:
Let
and
denote the coordinates of these two points, respectively.
Calculate the slope
of this line:
.
Notice that the slope is zero because the two points have the same
-coordinates (
) even though their
-coordinates are distinct (
.)
Equation for this line in point-slope form:
.
.
Rewrite and simplify to obtain the equation of this line in slope-intercept form:
.
The
-term was eliminated because the slope was zero.
We can work out the circumference of the wheel by using the equation
C = πd
C = π × 2
C = <span>6.28318530718
C = 6 feet
If 1km is 3280 feet, 2km is 6560 feet
6560 </span>÷ 6 = <span>1093.33333333 (recurring)
= 1093
Therefore the bike wheels rolls (approximately) 1093 times to cover 2km.
