this is the question:
Given that A(0,-3) and B(-10,-28) are two points that lie on a straight line in x and y space, find:
(a) The slope of the line
(b) The intercept
(c) The equation for the straight line
(d) Sketch the line
I uset his formula c = y1 - y2 / x1 - x2 = 25/10
so y = a - 25/10x
the slope of the line is 25/10x
how do i find the intercept( is there a formuala to this), and also the quation for the stright line.
I am assuming the "d" will be answered by doing "c" should that shouldn't be a problem.
I would really appreciate your help.
