Answer:

Step-by-step explanation:
From the graph,
The initial red incline is a straight line passing through the origin.
So, a straight line passing through the origin is of the form:

Where, 'm' is the slope.
Now, the slope of a given as the change in y value to change in x value.
Consider the two end points of the red line (0, 0) and (4, 6).
The slope with two points
on the line is given as:

Plug in
. Therefore, slope is:

Hence, the equation of the initial red incline is:

Ya I think it is also the second one
Because there are 3 feet in a yard, 7 yards of fabric is 21 feet. Since she already has 2 feet of fabric, she will need 19 more feet of fabric.
