Question

Write the standard form of the line that contains a slope of -3/8 and passes through the point (5, -4). include your work

1 Answer

  • y = mx + b
    slope(m) = -3/8
    (5,-4)...x = 5 and y = -4
    now we sub and find b, the y int
    -4 = -3/8(5) + b
    -4 = -15/8 + b
    -4 + 15/8 = b
    -32/8 + 15/8 = b
    -17/8 = b

    y = -3/8x - 17/8.....add 3/8x to both sides
    3/8x + y = -17/8...multiply everything by 8
    3x + 8y = - 17 <=== standard form
