Answer 1

Looking for help to or answer with explanation

Answer 2

for problems like this.. I would just copy and paste them into the input line on geogebra to cross check them..

Answer 3

Find the gradient of the line using the formula, m= y2-y1/x2-x1
than to find the equation use this formula, y-y1= m(x-x1)
