Question

What is the equation of a line that passes through (-10,3) and is parallel to y =2x+9?

Answer 1

-2/3.

Explanation:

Answer 2

• y = 2x + 23

Explanation:

Given

• Line y = 2x + 9

Parallel line has same slope

• y = 2x + b

Finding b using the given point (-10, 3)

• 3 = 2(-10) + b
• 3 = -20 + b
• 3 + 20 = b
• b = 23

So the line is:

• y = 2x + 23
