The equation of the line with a slope of 14 and a y-intercept of 0 is y = 14x. This line indeed passes through the origin, as all lines of the form y = mx do. For any value of x, the corresponding point on the line can be calculated using the equation. Specifically, when x equals 0, the point is (0,0), confirming it goes through the origin. This reinforces the understanding of linear equations in slope-intercept form.

Given slope = 14; y-intercept is 0, find the equation of the line.

Solution:

y = mx + b

y = 14x + 0

y = 14x

The equation of the line is y = 14x.

Correct?

Of course it is!
 
Does the line y = 14x go through the origin?

All lines of the form $y=mx$ go through the origin...for any $x=a$, the point $(a,ma)$ is on the line...what point do we get if $a=0$?
 
Good information for my notes.
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
