zero x-intercept also zero
y = -4x The y-intercept is zero. That is, the graph passes through the origin.
4x = y : or it can be written in the reverse order, y = 4x.

The perimeter of the triangle is 8x + 4y. The measures of two of the sides are x + 2y and 3x + y. If these two sides were added together, they would be 4x + 3y:x + 2y3x + y4x + 3yThe third side is the perimeter minus the two known sides, so 8x + 4y - (4x + 3y). Distribute the negative: 8x + 4y - 4x - 3y. This is equal to the third side, which is 4x +y.
