Answer:
B. y = -3/4x + 5/2
Step-by-step explanation:
Take two points from the graph, let's use (-2, 4) and (2, 1):
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (2 - (-2))
= -3/4
Find y-intercept using slope above and anyone point:
y = mx + b
(1) = -3/4(2) + b
1 = -3/2 + b
b = 1 + 3/2
b = 5/2
Equation of line using m and b above:
y = mx + b
y = -3/4x + 5/2

Answer:
y = x - 5
Step-by-step explanation:
The equation of the line parallel to the line
is
.
That is, equations of parallel lines differ only by constant.
The given equation is 
This is written as 
Therefore, the equation of the line parallel to this line is given by 
The value of c is determined using the point given.
Substituting the point (3,-2) we get:


Therefore, the equation of the line becomes y = x - 5.
