Classify each decreasing function as having a slope that is steeper or less steep than the slope of the function represented in this graph. y = - 4 3 ⁢ x + 2 3 y = - 3 2 ⁢ x + 1 2 y = - 2 ⁢ x + 7 3 y = - 7 4 ⁢ x + 3 2 y = - 8 7 ⁢ x + 4 7

To compare the steepness of the slopes of different lines, we need to compare the absolute value of the coefficient of the x-term (the number in front of x) in each equation. A larger coefficient of x means a steeper slope, while a smaller coefficient of x means a less steep slope.

y = - 4 3 ⁢ x + 2 3

The coefficient of x in this equation is - 4 3, this function has a steeper slope than the function y = - 3 2 ⁢ x + 1 2

y = - 3 2 ⁢ x + 1 2

The coefficient of x in this equation is - 3 2, this function has a steeper slope than the function y = - 2 ⁢ x + 7 3

y = - 2 ⁢ x + 7 3

The coefficient of x in this equation is - 2, this function has a steeper slope than the function y = - 7 4 ⁢ x + 3 2

y = - 7 4 ⁢ x + 3 2

The coefficient of x in this equation is - 7 4, this function has a steeper slope than the function y = - 8 7 ⁢ x + 4 7

y = - 8 7 ⁢ x + 4 7

The coefficient of x in this equation is - 8 7, this function has the least steep slope of all the functions.

So the order of the functions from steepest to least steep is: y = - 4 3 ⁢ x + 2 3 , y = - 3 2 ⁢ x + 1 2, y = - 2 ⁢ x + 7 3, y = - 7 4 ⁢ x + 3 2 , y = - 8 7 ⁢ x + 4 7
