Answer is table 4

Step by step

Y1 is y = 4x -9
Y2 is y = 2x - 5

Our coordinates are (2,-1)

To find if the solution is true for each table, plug the solution in for y1 and y2

Table 1

Y1 is -13 = 4(-1) -9 = -13 ✅
Y2 is -13 = 2(-1) -5 = -7 ❌ stop no solution

Table 2

Y1 is -13 = 4(-1) -9 = -13 ✅
Y2 is -7 = 2(-1) - 5 = -7 ✅

Y1 is -9 = 4(0) -9 = -9 ✅
Y2 is -5 = 2(0) - 5 = -5 ✅

Y1 is -5 = 4(1) -9 = -5 ✅
Y2 is -3 = 2(1) - 5 = -3 ✅

Y1 is 3 = 4(2) - 9 = ❌
Y2 is 1 = 2(2) - 5 = ❌ stop no solution

Table 3

Y1 is -13 = 4(-1) -9 = -13 ✅
Y2 is -7 = 2(-1) - 5 = -7 ✅

Y1 is -9 = 4(0) -9 = -9 ✅
Y2 is -5 = 2(0) - 5 = -5 ✅

Y1 is -5 = 4(1) -9 = -5 ✅
Y2 is -3 = 2(1) - 5 = -3 ✅

Y1 is 1 = 4(2) -9 = -1 ❌
Y2 is 1 = 2(2) - 5 = -1 ❌ stop no solution

Table 4

Y1 is -13 = 4(-1) -9 = -13 ✅
Y2 is -7 = 2(-1) - 5 = -7 ✅

Y1 is -9 = 4(0) -9 = -9 ✅
Y2 is -5 = 2(0) - 5 = -5 ✅

Y1 is -5 = 4(1) -9 = -5 ✅
Y2 is -3 = 2(1) - 5 = -3 ✅

Y1 is -1 = 4(2) -9 = -1 ✅
Y2 is -1 = 2(2) - 5 = -1 ✅

Y1 is 3 = 4(3) -9 = 3 ✅
Y2 is 1 = 2(3) - 5 = 1 ✅

This table #4 has all solutions correct
