Unit 4 Mid

What is the equation of a line that passes through the point (4,2) and is parallel to the line whose equation is y = x/3 - 1

Question 7 options:

y = -3x + 14


y = x/3 - 23

y = 3/x - 23

y = -3/x - 23

Respuesta :

-----------------------
Find Slope :
-----------------------
y = x/3 - 1
slope = 1/3

-----------------------
Equation :
-----------------------
y = mx + b
y = 1/3 x + b

-----------------------
Find y-intercept :
-----------------------
y = 1/3x + b
at point (4, 2),
2 = 1/3(4) + b
b = 2 - 4/3
b = 2/3

-----------------------
Equation : 
-----------------------
y = 1/3x + 2/3
