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 terms are 2x 4y and 8 variables are x and y coefficients are 2 and 4 number is 8 hope this helped :)
Let y be the total money earned in a day and x be the pairs of shoes sold.
y = 4.5x + 40
Putting y = 112
112 = 4.5x + 40
x = 16 pairs of shoes must be sold to meet the requirement.
