Question

I don't understand how to do number 14. Please help!

Answer 1

so the equation to setup is y1-y2 /x1-x2=y/x so y1 is 0 minus y2 which is 0 which equals 0 over x1 which is -3 minus x2 which is 0 equals -3 and so the answer would be 0 over -3 or in graphing points(-3,0)

Answer 2

Since both points are on the x- axis the equation of the line would be y= 0.
