The car is speeding at a rate of 33.3mph
<h3>Speed and distance of an object</h3>
If a certain car going 60 mph can stop in 180 ft, then we can express this as:
To determine the speed for a car traveling at 100ft, we will have:
Take the ratio of the expression
60/x = 180/100
180x = 6000
x = 33.3mph
Hence the car is speeding at a rate of 33.3mph

Answer:
Step-by-step explanation:
slope-intercept equation for line of slope -5/2 and y-intercept -2:
y = (-5/2)x-2
put into standard form:
(5/2)x + y = -2
5x + 2y = -4
