Parallel lines have slopes that are equal to one another.
Slope intercept form is:
y = mx + b (where m = slope and b = y-intercept)
the equation of the 1st line
y = 3x + 4 so it’s slope (m) = 3
the problem tells us the y-intercept of the second line is -6.
so we plug the two knowns into slope intercept form to get the equation of the second line:
y = 3x - 6
I hope this helps and is the BRAINLIEST!
Great luck with your studies :)
