Please help! I've been stuck on this question for a long time! Anyone am expert in math? Haha! :)

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. t

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
