In the equation ax+by =c, if a and b are positive, and c is negative, which of the following are true? select all that apply.

a- the x-intercept is positive.
b- the x-intercept is negative.
c- the y-intercept is positive.
d- the y-intercept is negative.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

50-38=12
