How do you solve the system of equations by graphing and then classify the system as consistent or inconsistent #2x - 3y = 14# and #2x + y = -10#?
1 Answer
See a solution process below:
Explanation:
To graph the lines first find two points on the line. Then plot the points. Then draw a line through the points:
Equation 1:
For
For
graph{((x-1)^2+(y+4)^2-0.25)((x-4)^2+(y+2)^2-0.25)(2x-3y-14)=0 [-30, 30, -15, 15]}
Equation 2:
For
For
graph{(2x+y+10)(x^2+(y+10)^2-0.25)((x+5)^2+y^2-0.25)(2x-3y-14)=0 [-30, 30, -15, 15]}
We can see the the lines cross at
graph{((x+2)^2+(y+6)^2-0.05)(2x+y+10)(2x-3y-14)=0 [-16, 16, -8, 8]}
