Which equation describes the graph?

Someone me! if you’re smart you can solve this!

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Which shaded region is the solution to the system of inequalities? y y[tex]\geq[/tex]-x+1
