aripotta · Answer

you wanna convert the second equation into slope-intercept form: y = mx + b

anonymous · Answer

idk how to do that.

aripotta · Answer

ok, another way of saying it is solving for y. you want y by itself on the left side of the equation

aripotta · Answer

so to get rid of the 2, we're going to subtract 2 from both sides

y + 2 = -5x
y = -5x - 2

aripotta · Answer

so both of the equations are exactly the same

aripotta · Answer

what would our answer be, knowing that both lines have the same equation?

anonymous · Answer

b?

aripotta · Answer

no, it would be b if they had different y-intercepts. in this case, they have the same slope and y-intercept. the answer would be a.
