Equation of line
Let m represents the slope of the line;
m is calculated as thus
By substituting the right values in the formula above;
becomes
Multiply both sides by 
Reorder
Hence, the equation that represents the line is
The answer is 0.008a^3 because you would do 0.2 to the power of 3
3x-y=6, in order to be able to graph this you would have to change the equation to y=, so you need to subtract 3x from that side making it -y=-3x+6, now you need to y positive, so divide both sides by -1, thus making the equation look like y=3x-6, now if you can't plug this into a calculator to see what it would look like then you need to know what y=mx+b means. y is the equation you want to graph obviously, m = the slope, so our slope in this case would be -3, and b = our y intercept, so it would be (0,-6), so plot (0,-6) and use the slope to plot the rest of the points, some other points in this line should include (2,0), (-1,-9) and (4,6), just to name a few. Hope this helps.
