Me ! i'll give ! what is the best approximation of the solution to the system? (round to the nearest whole number). explain what is similar or different about the two lines. use the key vocabulary words: slope and y-intercept.

For the first question you best estimate would be : (1, 7) because these points are the closest co-ordinates to the real answer

Second question answer will be: The 2 lines have different slope, one is negative and another is positive. The y-intercepts for both equation are different but the x co-ordinate in both intercepts is 0

answer: sine

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
