    The slop intercept form of the line is

    y = mx + c

    here m is slop of the line and c is y intercept of the line so our equation is

    y = (-1/8)x + c

    Now the line passes through the point (9 , -7) so we can insert the (x,y) values into above equation to find the value of c , y intercept of the line.

    -7 = (-1/8)9 + c

    by solving it for c

    -7 = -9/8 + c

    we can write it as

    c = -7+9/8

    c = -5.875
