One linear function, t(x), can be modeled by the values in the table below. A second linear function can be modeled by the equation 4x − 5y − 20 = 0. When comparing the x-intercepts of these lines, which function has the largest x-intercept and what is this value? x t(x) −2 −16 −1 −12 0 −8 1 −4 2 0 A: t(x) has the largest x-intercept: −8. B: 4x − 5y − 20 = 0 has the largest x-intercept: 5. C: t(x) has the largest x-intercept: 2. D: 4x − 5y − 20 = 0 has the largest x-intercept: −4.

the x intercept for t(x)   is when t(x) = 0  and form thr table that is -8. to find the x intercept for  4x - 5y - 20 = 0   we find x when y = 0:- 4x - 5(0) - 20 = 0 4x = 20  x = 5 so the correcr choice is B
