Question

If line f is parallel to the line h, and line f has y-intercept 5, what is the equation of line f ? With h passing h through two points (1, 2) and (3, 6)

Answer 1

from the two given points you should be able to find the slope m

Since your new line is parallel to the above, the value of m must be the same

so just write down
y = mx + 5 , where m is the value you found for the slope.
