What is the x-intercept of this line?

y = (2/3)x - 2

Step-by-step explanation:

Next time please present your table in actual tabular form:    x         y

As we move from (-3,-4) to (6,2), x (the run) increases by 9 and y (the rise) increases by 6.  Thus, the slope of the line segment connecting these two points is m = rise / run = 6/9, or  m = 2/3.

Start with the slope-intercept form of the equation of a straight line:

y = mx + b  =>  2 = (2/3)(6) + b             and find b:

2 = 4 + b, so b = -2, and the desired equation is    y = (2/3)x - 2

where is the figure

to determine the unit cost your would divide the total cost by the number sold.
