Need i don't get it. which point is an exact solution to the system y = -6(0.75)^x and y = 4(x - 1)? (0, -6) (-1, -8) (-2, -12) (-4.5, -22)

Answer (-1 , -8)


Check Equation -6(0.75)ˣ

when x = -1
y = -6(0.75)⁻¹
y = -6(4/3)
y = -8

When x = -1, y = -8, therefore this equation passes through (-1, -8)


Check Equation y = 4(x - 1)

When x = -1 
y = 4( - 1 -1)
y = 4(-2)
y = -8

When x = -1, y = -8, therefore this equation passes through (-1, -8)


Answer (B): (- 1, -8)
