Question

Find the equation of a line that is parallel to y = 5x + 7 and passes through (4, 3)

Answer 1

Answer:

B) y=5x-17

Step-by-step explanation:

I got this answer, by first making sure it was parallel to y=5x+7. Which was easy because the only thing they need to be parallel is the same slope, in this case was 5. Next I pluged in (4,3) to y=5x-17. I substituted 4 into x and got 20. Then I substituted 3 into y. Since 20-17 is equal to 3, then B. is your answer.

Answer 2

Answer:

y = 5x - 17

Step-by-step explanation:

1. Find b using the slope of 5 (parallel lines have the same slope) by plugging the slope given and the point (4,3) into y = mx + b

3 = 5 ( 4) + b

3 = 20 + b

-17 = b

2.  Plug m and b into the equation y = mx + b

y = 5x - 17
