Answer:
(0, -1) and (3, -8)
Step-by-step explanation:
7x + 3y = -3 and y = -2^x
LEts check with each option
(-1, 0) and (-8, 3)
y=-2^x , plug in x=-1
y= -2^-1 =-1/2 is not equal to 0
(0, -1) and (3, -8), plug in (0,-1)
y=-2^x = -2^0 = -1, so (0,-1) satisfies the equation y=-2^x
LEts check with equation 7x+3y = -3
7(0)+3y =-3
3y=-3 so y =-1
Hence (0,-1) satisfies the both equation
LEts check with (3,-8)
y=-2^x= -2^3= -8
7x+3y=-3
7(3)+ 3y=-3
21 +3y=-3
3y=-24 so y = -8
(3,-8) also satisfies both equations
