Answer:
lines are not parallel
Step-by-step explanation:
y = 5x + 6
–18x + 3y = –54
When the lines are parallel then the slope are equal
LEts write the equation in slope intercept form y=mx+b, where m is the slope
y= 5x+6
slope of the first line is 5
–18x + 3y = –54
Add 18x on both sides
3y= 18x-54
Divide whole equation by 3
y= 6x -18
Slope of the second line is 6
Slope of first line not equal to the slope of second line
So the lines are not parallel
