Figure A maps the figure B with a scale factor of 1.75

Given a(-12,5) and b(12,29) find the point that divides the line segment ab three-eighths of the way from a to b

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?

Aquadratic equation in standard from is written ax^2= bx+c, where a,b and c are real numbers and a is not zero?
