The given equation is of the form y = m x + b where m is the slope and b is the y intercept that is value of y when x =0 , or we can say b is the initial value.
In the given equation which is y = 4t+2, on comparing we will get m =4 that is slope is 4 and here slope represents the rate or speed and 2 is the y intercept that is b. And 2 represents the initial position that is, the ant is 2 units from the home initially .
The regular price is 5 for $2.95. One can is $2.95/5 = $0.59. Three cans are $1.77. With the $1 rebate, the final price would be $0.77 for 3 cans, $0.25 per can.
Considering the picture attached, the distance to Cascade Falls is written in mixed fraction and the question wants it expressed in decimal. is same as 1 divided by 2 which is 0.5 hence the fall is 3+0.5=3.5 miles
