The coordinates of several stars drawn in a coordinate plane are $\left(8,0\right),\left(7,-3\right) ,\left(3,-2.5\right),\left(3.5,0.5\ right),\left(-1,3\right),\left(-3,5 \right)$ and $\left(-7,6\right)$ . Plot the locations of the stars. Draw a constellation by connecting the points in order. Also connect the points $\left(8,0\right)$ and $\left(3.5,0.5\right)$ .

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
