To find the equation of a line when having the slope and a point, we use the point-slope equation:
Where m is the slope and (x1,y1) is the point.
In this case, since the point is (0,0):
And we are told that the line is parallel to a line that has a slope of -6. Something that is important to solve this problem is:
• Parallel line have ,the same slope
So the slope of the line is also -6:
Now we are ready to use the point-slope equation:
Substituting m, x1, and y1:
Simplifying the expression, we get the slope-intercept form:
Answer: y=-6x
