Answer:
[tex](7,-12)[/tex]
Step-by-step explanation:
We have been given a system of equations. We are asked to solve the given system by graphing.
[tex]y=-3x+9...(1)\\y=-x-5...(2)[/tex]
We can see both equations are in slope-intercept form of equation.
The line of equation [tex]y=-3x+9[/tex] will cross the y-axis at (0,9) and will have a slope of [tex]-3[/tex].
The line of equation [tex]y=-x-5[/tex] will cross the y-axis at [tex](0,-5)[/tex] and will have a slope of [tex]-1[/tex].
Please find the attachment for the graph of both equations.
We can see that both lines intersect at point [tex](7,-12)[/tex], therefore, the solution of our give system is [tex](7,-12)[/tex].
