Find an equation of the line (in slope-intercept form) that passes through the point (7,5) and is perpendicular to the line 7x + 10y - 17 = 0

y=?

  • math -

    consider the line:
    7x+10y-17=0
    y=-.7x+1.7
    so the slope of the perpendicular line is
    m=+10/7
    y=10/7 x + b put in y, x given, solve for b, and you have the equation of the lline
    y=10x/7 + b
