Line m passes through c(-2, 0) and d(1, -3). write the equation of the line m in standard form.

(-2,0),(1,-3)
slope = (-3 - 0) / (1 - (-2) = -3 / (1 + 2) = -3/3 = -1

y = mx + b
slope(m) = -1
use either of ur points(-2,0)...x = -2 and y = 0
now sub into the formula and find b, the y int
0 = -1(-2) + b
0 = 2 + b
-2 = b
so ur equation is : y = -x - 2...but we need it in standard form

y = -x - 2add x to both sides
x + y = -2 <== standard form
