Answer:
Explanation:
a)
m = y2-y1 / x2-x1
P1 = (3,-4) as (x1,y1)
P2= (5,6) as (x2,y2)
m = 6-(-4) / 5 - 3)
m = 6+4 / 2
m = 10 / 2
m = 5
b)
m = y2-y1 / x2-x1
P1 = (5,-3) as (x1,y1)
P2= (5,6) as (x2,y2)
m= 6-(-3) / 5-5
m = 6+3 / 0 ( the world blows up when you divide by zero :0 undefined )
c)
m = y2-y1 / x2-x1
P1 = (1,-1) as (x1,y1)
P2= (8,-8) as (x2,y2)
m = -8-(-1) / 8-1
m = -8+1 / 7
m = -7 / 7
m = -1
d)
m = y2-y1 / x2-x1
P1 = (-2.8,2) as (x1,y1)
P2= (-1.2,2) as (x2,y2)
m = 2-2 / a number 0 because the numerator is 0 and there is a number in the denominator
e)
m = y2-y1 / x2-x1
P1 = (c,d) as (x1,y1)
P2= (e,f) as (x2,y2)
m = f-d / e-c that's all you can do until we're given those variables
f)
m = y2-y1 / x2-x1
P1 = (0,c) as (x1,y1)
P2= (d,0) as (x2,y2)
m = 0-c / d-0
m = -c /d
