def x_int (m,b):
    x= -b/m
    return x

The x-intercept of any line is where the y value is 0

to find the x intercept, we then simply solve for x if the equation of the line is in point-slope form

this code assumes y is zero and just calculates for x when given m and b

for a line y=4x+5:

x_int(4,5)

-1.25

For a line y=100x+20:

x_int(100,20)

-0.2
