Write the slope intercept equation of the function f whose graph satisifies the given conditions. The graph of f passes through (-8,6) and is perpendicular to the line that has an x-intercept of 1 and a y-intercept of -2.

Slope intercept form

its 4 because 2 times 2 is 4, if you double the number two you get four

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
