Answer:
Marty's with a slope of 1/3
Step-by-step explanation:
The functions Marty and Ethan wrote are analyzed the find the slope of each of the function
The equation Marty wrote is presented here as follows;
Marty's equation can be written in slope and intercept form, <em>y = m·x + c</em>, as follows;
By comparison, the slope of the function, m = 1/3
Marty's function has a slope of m = 1/3
Ethan has the following two column table;
The slope, <em>m,</em> of the data in the above table is given as follows;
Taking any two points, (x₁, y₁) = (-4, 9.2), and (x₂, y₂) = (2, 10.4), we get;
Ethan's function has a slope of m = 1/5
Therefore;
Marty's slope of 1/3 is larger, given that 1/3 > 1/5.
