What is an equation for the linear function whose graph contains the points (−1, −2) and (3, 10)

The equation of a line starting from two points is:


From the first point you get: x1 = -1, y1 = -2
From the second point you get: x2 = 3, y2 = 10

Replace x1, y1, x2, y2 in the equation of the line and you get:




From this you get the equation of your line:
