Question

Write th equation of the line in standard from passing through the point (-1,2) and is parallel to the line: y=3x-5

Answer 1

y = 3x + 5

Explanation:

Parallel ⇒ Same gradient

→ Rewrite with the same gradient but different constant

y = 3x + c

→ Substitute in the new coordinates

2= -3 + c

→ Solve for c

c = 5

→ Rewrite full line equation

y = 3x + 5
