Question

Write the equation of the line passing through (−1, 0) and (0, −3).

Answer 1

y = -3x -3

Explanation:

We have two points so we can find the slope

m = (y2-y1)/ (x2-x1)

m = (-3-0)/(0--1)

= (-3-0)/(0+1)

= -3/1

= -3

We have the slope and the y intercept (where x=0) The y intercept is -3

y = mx+b where m is the slope and b is the y intercept

y = -3x -3
