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.

Respuesta :

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
