Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.

y - 1 = 4(x - 3)

y + 1 = 4(x + 3)

y - 3 = 4(x + 1)

y + 3 = 4(x - 1)

mrnood · Answer

what do oyu know about the equation for a straight line y=mx+b?

anonymous · Answer

so i put it into y= mx+b and then plug in the numbers

mrnood · Answer

from the original data (slope and intercept - write the equation in y=mx+b form

THEN

Rearrang all the answers into the same form - one of them will be th e same as your equaiton

anonymous · Answer

alright

anonymous · Answer

can you transform one of the equations into y +mx+b and tell me how to do it so i can do the other ones

anonymous · Answer

$$ y - 1 = 4(x - 3)$$ distribute on the right 
$$y-1=4x-12$$ add $1$ so solve for $y$
$$y=4x-11$$ steps are always the same

anonymous · Answer

alright thank you:)
