Using the graphing function on your calculator, find the solution to the system

stealth61 [152]

Answer:

It has infinite solutions.

D. More than 1 solution

Step-by-step explanation:

$\left \{ {{3y - 9x = -6} \atop {5y - 15x = -10}} \right.$

$\left \{ {{3y(-5) - 9x(-5) = -6(-5)} \atop {5y(3) - 15x(3) = -10(3)}} \right.$

$\left \{ {{-15y +45x = 30} \atop {15y - 45x = -30}} \right.$

$0+0=0$

$5y = 15x - 10\\y = 3x - 2$

$3(3x-2) - 9x = -6$

$0=0$
