She is wrong because 3 times the perimeter of one triangle is the sum of 9 sides of the triangles.

In the shape we see that some of the sides of the triangles are 'shared' and dare not part of the perimeter of the shape, - the perimeter is only the length of 5 sides of a triangle.

So the perimeter is less than the sum of the sides of the 3 triangles.

Write the equation in slope-intercept form: 4x -2y =12

DedPeter [7]

$4x - 2y = 12 \\ \: \: \: \: \: \: \frac{ - 2y}{ - 2} = \frac{ - 4x}{ - 2} \: + \frac{12}{ - 2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: y = 2x - 6$

Therefore, the answer is 1) y = 2x - 6
