Question 821603: Find the coordinates of three more points that lie on the line passing through the points (2, −1) and (−3, 4).
i have no idea whatsoever on how to do this.

given the points: (2, -1) and (-3, 4)
---
to solve the linear equation, copy and paste this (the two points given):
2, -1, -3, 4
into the "Two-Point form: x1 y1 x2 y2" input box here: https://sooeet.com/math/linear-equation-solver.php
---
answer:
x-intercept = 1
y-intercept = 1
slope = -1
---
the point-slope form of the line:
y = -x + 1
---
two easy additional points are the intercepts:
x-intercept = (1,0)
y-intercept = (0,1)
for a third additional point, just pick any x and solve for y:
x = 2
y = -x + 1
y = -2 + 1
y = -1
(2,-1)
---
answer:
three points:
(1,0)
(0,1)
(2,-1)
