Answer:

$(2,\infty)$

Step-by-step explanation:

After x=2, we see that the change in y over the change in x is positive since both variables increase with each other, so $(2,\infty)$ is where the function is increasing.

Answer:

5(x+1) -2(y-3) = 0

Step-by-step explanation:

For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

5(x+1) -2(y-3) = 0
