Answer:
8
Step-by-step explanation:
The slope point form is

m is the slope
x1, y1 are the coordinates of a point on the line
The slope of the line is -1
m = -1
point (-5, -4) lies on the line
x1 = -5 and y1 = -4
Let us substitute them in the form above

Remember (-)(-) = (+)

The equation of the line in the slope-point form is y + 4 = -1(x + 5)
I mean...the number ends in a even number, you could go by 2's, or is that not what you mean. I can help you some other way if you could explain a bit more :)
3.5x=42
x represents the length, since the formula to find area of a rectangle is width times length.
