Answer to Question #24726 in Abstract Algebra for Brandon Phillips

Question #24726
Assume that y varies directly with x. If y = 910 when x =2, y=34 when x =7.
Expert's answer
Since y varies directly with x, then their dependence is described by linear function y=kx+b.

Since we have that y = 910 when x =2, y=34 when x =7, then we can substitute these points in our linear function:
Subtracting first out of second, and dividing by 5, we have that:

As we have now value of k, from first equality we have:


With obtained coefficients we can describe y as y=(-175.2)x+1260.4
