Question

ย 4.6.3 Test (CST): Linear Equations Question 19 of 25 What is an equation of the line that is parallel to y= 3x-8 and passes through the point (4, -5)? A. y = 3x - 7 B. y = 3x + 7 C. y = 3x - 17 D. y = 3x + 17 SUBMIT

Answer 1

y= 3x - 8

slope intercept formula:

y=mx+b

Where:

m= slope

b= y-intercept

Parallel lines have equal slopes:

y= 3x + b

Replace ( x,y) by the given point (4,-5) and solve for b

-5 = 3(4) + b

-5 = 12 +b

-5-12 = b

-17 = b

Final equation

y= 3x - 17

C. y = 3x - 17
