Suppose that n is a positive integer such that in base 7, then n can be expressed as overline{ABC}_7, and in base 11, then n can be expressed as overline{CBA}_{11}. Find the largest possible value of n in base 10.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
