Answer:
y = -3x +5
Step-by-step explanation:
parallel lines so slope of the lines will be equal.
m1 = m2
y = mx + b,
y = -3x + b
substituting y = -1 and x = 2
-1 = -3(2) + b
-1 = -6 + b
therefore, b = -1 + 6
b = 5
by substituting b = +5
therefore, the equation is,
y = -3x + 5
I believe it would be the third one
all you just have to do is divide 30 by 2 which is=15
and 40 by 4=10
50 by 10=5

Answer:
Answer: B
Step-by-step explanation:
The y intercept must be 0. The y intercept for a = - 2. This is not
a proportional relationship
The same comment can be made for C. The y intercept is 1. So C is not the answer.
