Answer:
See explanation
Step-by-step explanation:
1) Equation of line through (3, 2) with slope -2.
y = mx + b
2 = -2(3) + b
2 = -6 + b
8 = b
y = -2x + 8
2) Equation of the line through the points (4, 2) and (3, 1)
m = (1 - 2)/(3 - 4) = -1 / -1 = 1
y = mx + b
1 = 1(3) + b
1 = 3 + b
-2 = b
y = x - 2
Answer:
y=-2x+8
y=x-2
Step-by-step explanation:
y=-2x+b
2=-2(3)+b
2=-6+b
8=b
Plug it into your expression
y=-2x+8
(1-2)=m(3-4)
-1=m(-1)
-1=-m
1=m
Plug it into your expression
y=1x+b
1=1(3)+b
-2=b
Plug it into your expression
y=x-2
