Answer:

A) y+7=-3(x-4)

Step-by-step explanation:

Hi there!

The given equations are written in point-slope form: y-y_1=m(x-x_1) where <em>m</em> is the slope of the line and (x_1,y_1) is a point that falls on the line

Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.

Therefore, the equation of the line is either A or B.

Now, let's look at A:

y+7=-3(x-4)

This equation suggests that the point (4,-7) falls on the line, which it does.

Therefore, the equation of the graph is y+7=-3(x-4).

I hope this helps!

What is the diagonal of a right triangle
bekas [8.4K]

Answer:

diagonal of a polygon is a line from a vertex to a non-adjacent vertex. So a triangle, the simplest polygon, has no diagonals. You cannot draw a line from one interior angle to any other interior angle that is not also a side of the triangle.

Step-by-step explanation:

To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse. Then solve for c
