solve each system firs by graphing, then using algebra. y=3x+1 and y=-2x+-4

Answer 1

y = 3x+1

y =-2x-4

1st equation is upward sloping with y intercept = 1

2nd equation is downward sloping with y intercept =-4

they are like a slim, vertically elongated cross, an "X" where the intersection is the point (-1,-2)

subtract the two equations

0=5x+5

x=-1

y=-2
