is the relationship between the width and length of the patio linear? Why or why not

Answer:
The relationship is not linear.
A linear relationship can be represented by
y = k*x
Which means that the increments or decrements of x, have a proportional gain that corresponds to the changes of y
In the case of the picture
The length
l = 2*w - 5
has the same appearance as the slope intercept form of the equation of the line. However, the constant -5 adds a negative offset to the graph that dissolves the linearity between the variables l and w.
Answer:
The relationship is linear
Step-by-step explanation:
Because there are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. This one is showing slope-intercept form
Point-slope form = y-y₁=m(x-x₁)
Standard form = Ax+By = C
Slope-intercept form = y = mx + b
