Consider the line with equation
5x – 2y = 10.

(a) Find the y-intercept for the given line.

(b) Find the slope for a line parallel to the given line.

(c) Find the slope for a line perpendicular to the given line.

  • Algebra - ,

    y intercept is when x = 0
    -2y = 10
    y = -5

    2 y = 5 x - 10
    y = (5/2) x = 5
    so m, the slope, = (5/2)

    m'= -1/m
    m' = -2/5

    This is interesting, I got the first one correct for y = -5 because x = 0 but still do not get how you come up with 5/2 for the slope of the parallel line and the slope of the perpendicular one either? Can you please explain. Thanks!
