Question

Write an equation for the line in slope-intercept form, given that the line passes through the point (2,3) and (3,4).


y = -x + 1

y = x + 1

y = x – 1

y = 2x + 1

Answer 1

Hint : try and calculate slope = change in y-coordinate divided by change in x-coordinate.
Then you can use one of the two formulae that I have given in the two previous questions

Answer 2

There is a general formula for this sort of question, but it can be trivially derived from the other two
