Question

Write the equation in slope-intercept form of the line that is perpendicular to the line 7y+4x=3 and passes through the point (-4,-7).

1 Answer

  • 7y + 4x = 3 => y = -4/7 x + 3/7
    Then, slope=-4/7
    So the new slope should be 7/4 (opposite reciprocal)

    y= 7/4 x + b
    Using (-4,-7) => -7 +b = -7 => b = 0

    So the new equation would be:
    y=7/4 x
