Question

y=-5x - 13,7x+2y=-23*Different / Different(-1,-8)(4.10)One PointAl PointsSame/ differentInfinite Solutions

Answer 1

1) Let's solve this Linear System of equations

y=-5x-13

x+2y=-23

2) Using the method of Substitution on the 2nd equation

x +2(-5x-13) = -23

x -10x -26= -23

-9x -26 =-23 Add 26 to both sides

9x=-23+26

9x = 3

x= 3/9

x= 1/3

y=-5(1/3) -13

y=-5/3 -13

y=-44/3

3) So there is one solution to that Linear System, different than those points (-1,-8) (4,10).
