Without graphing or solving either system of equations explain how you know what the solution to the system is. y = -x +4
y = -2 + 1

x = 5

y = -1

Step-by-step explanation:

from second equation,

y = -2 + 1 y = -1

by putting the value of y in first equation

y = -x + 4-1 = -x + 4-x = -1 -4-x = -5x = 5

x = 5 and y = -1

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !

Ithink the answer is c just trying to others
