    Right.... and you know what x1 and y1 are since they gave you the coordinates. So plug it in.... y-y1=m(x-x1)

    y-(-4)=-1/3(x-6) y+4=-1/3(x-6) @itsjustme_lol do you understand that?

    It is a negative being multiplied by a negative. That is something you should be familiar with.

    y+4=-1/3(x-6) *We must first distribute that -1/3 on the right side of the equation. y+4=-1/3x+2 Now we need to make this equation into the slope-intercept form... so y=mx+b... so lets subtract the 4 from both sides. y+4=-1/3x+2 -4 -4 --------------------- y=-1/3x-2
