1) Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 6/1 so this line "cuts" the y axis at y= 6.00000

  y-intercept = 42/7 = 6

Calculate the X-Intercept :

When y = 0 the value of x is -42/1 Our line therefore "cuts" the x axis at x=-42.00000

  x-intercept = -42/1 = -42.00000

2) Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 2/-1 so this line "cuts" the y axis at y=-2.00000

  y-intercept = 6/-3 = 2/-1 = -2.00000

Calculate the X-Intercept :

When y = 0 the value of x is 6/1 Our line therefore "cuts" the x axis at x= 6.00000

  x-intercept = 6/1 = 6.00000
