Answer:

  -25 dollars per month

Step-by-step explanation:

It is convenient to compute the rate of change using points where the graph crosses grid intersections. A couple of these are ...

  (months, dollars) = (1, 675)  and  (4, 600)

Using the slope formula, we have ...

  m = (y2 -y1)/(x2 -x1)

  m = (600 -675)/(4 -1) = -75/3 = -25 . . . . . dollars/month

Using a straightedge draw a random triangle now carefully cut it out next amputate the angles by snipping through adjacents side
Nezavi [6.7K]
This is usually used as a proof that triangles have 180°.  Look at the attached figures.  If you cut off angle A, angle B and angle C and rotate them so that their vertices touch, you form a half-circle out of them (or a straight line).  We know that half a circle is 1/2 of 360° or 180; therefore all 3 angles in a triangle must add up to 180°.
