Question

Input in standard form the equation of the given line.

The line through (0, -3) and (3, 0)

Answer 1

say given points are A(x1,y1) and B(x2, y2). then the equation of line passing through A and B is (y-y1)/(y2-y1) = (x-x1)/(x2-x1)

Answer 2

try otherwise i will help!

Answer 3

help:(

Answer 4

lol, alright.
find the slope:

0-(-3)
-----
3 - 0

equals 1

Answer 5

y = mx + c
-3 = 1(0) + c

c = -3

Answer 6

now, y = mx + c

y = x -3

Answer 7

given points are (x1,y1) = (0,-3) and (x2, y2) = (3,0).
So x1=0, y1=-3, x2=3, y2=0;
that gives (y-(-3))/(0-(-3)) = (x-0)/(3-0)
(y+3)/3 = x/3
y+3=x
y=x-3
