Answer:
When the line intercepts the x axis, this means that y will be 0.
therefore the 2 coordinates the line passes through are (2,-5) and (4,0)
given equation of line:
y=mx+b
where m = slope
b = y-intercept.
Let (2,-5) and (4,0) be (x1,y1) and (x2,y2) correspondingly.
slope of line = y1-y2 / x1 - x2

Now substitute x = 4, y = 0 and m = 5/2 into equation of line to find b.

therefore equation of line will be:

For A I think it should be 0.16 you just have to look at the chart
The horizontal asymptote is the line which the curve approaches to cross but never crosses the boundary. The horizontal asymptote can be identified when the exponent in the denominator<span> of the function is larger than the exponent in the numerator. If not, no horizontal asymptote exists. WHen there is, we equate the denominator to zero and get x</span>
The y axis is the horizontal line and the line of best fit intersects the y axis to give the y intercept at 8.
