Q=50-5P. Solve the equation for P

Choose the right one

P=50-Q

P=50+Q

P=10-5Q

P=10-(1/5)Q

P=50-5Q

• Algebra -

q=50-5P

subtract 50
q-50=-5P
divide by -5

-1/5q-50/-5=P
-1/5Q+10=P

Thank You, I thought that was but not 100% sure because I get backwards on the positive and negatives, Do you know how I find out the slope of the line or would graph it then?

• Algebra -

If you plot P on the horizontal (x) axis, and Q on the vertical (y) axis, then the slope is -(1/5).

• Algebra -

so it is negative then? -(1/5) Thank You
