Time Distance Distance / Time
2hrs 90 miles 90 miles / 2 hrs = 45 miles / hr
3hrs 135 miles 135 miles / 3 hrs = 45 miles / hr
5hrs 225 miles 225 miles / 5 hrs = 45 miles / hr
6hrs 270 miles 270 miles / 6 hrs = 45 miles / hr
Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.
Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt
Constant of proportionality is k which is D/T
d = 45t
Answer:slope=10.000/2.000=5.000
x-intercept=2/5=minus 0.40000
y-intercept=2/1=2.00000
Step-by-step explanation:
What is the thing to estimate?
to get the equation of any straight line, we simply need two points off of it, let's use the ones provided in the picture below.
Answer:
Slope: -1/3 y-intercept: (0,3) x-intercept: (9,0)
