Answer :
a line that is paralell would have the same slope, so the slope is -3, but different y intercept
so y=-3x+b
subsitte 1 for x and -2 for y
-2=-3(1)+b
-2=-3+b
add 3 to both sides
1=b
the equationis
y=-3x+1
so y=-3x+b
subsitte 1 for x and -2 for y
-2=-3(1)+b
-2=-3+b
add 3 to both sides
1=b
the equationis
y=-3x+1
