    * Find the equation of the straight line that has slope m = 4 and passes through the point (–1, –6). They've given me m = 4, x1 = –1, and y1 = –6. I'll plug these values into the point-slope form, and solve for "y=": y – y1 = m(x – x1) y – (–6) = (4)(x – (–1)) y + 6 = 4(x + 1) y + 6 = 4x + 4 y = 4x + 4 – 6 y = 4x – 2 Cop

    this is called the point slope formula y – y1 = m(x – x1)

    y-6=-3(x-(-1) y+6=-3(x+1) y+6=3x+1 y=3x+4+1 y=3x+5

    ok, so you knew what you were doing, but you messed up on the second line. you dont make -6, to +6. They did that, because it was already a negative, so it becomes a positive( y-(-3) become y+3
