1. Graphing the two leads to the following picture:
2. ANSWER: Based on the graph, the two lines intersect at point (1,-5) or x=1 and y=-5.
Check if the point (1,-5) satisfies the equations:
5x-y=10 so 5*1-(-5) then 5+5=10 which is a true statement.
5x+6y= -25 so then 5*1+6*(-5)=5-30=-25 which is a true statement.
So the intersection point (1,-5) is a solution to the system of equations.
I hope the above steps and explanation were helpful.
