What is a linear equation?
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Gale thought that it would be fun to go to the carnival.
The carnival cost $15.50 for the first person and $12.00 for each additional person.
Equation: c = 15.5 + 12f
Where c is the cost and f is the number of friends.
If the input of the equation is 3.
Then the value of the cost c will be
c = 15.5 + 12 × 3
c = 15.5 + 36
c = 51.5
Then the value of the cost c will be $51.5.
