9x+16y=72 slope intercept form

Slope= is or should be -1.125/2.000=-0.562 in then the x intercept should be = 72/9=8 and the y intercept should be = 72/16= 9/2 which equals to about 4.50000 and if u short that = 4.5) If I’m wrong plz let me know

The answer is 10. and if you go by pemdas you would 1. multiplication 2. division 3. addition 4. subtraction

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
