Which of the following equations is equivalent to the slope formula

Mathematics
1 answer:
tresset_1 [31]3 years ago
8 0

Answer: D

Step-by-step explanation: Notice that if you multiply both sides of the equation of y2 = m (x2 - x1) + y1 by X2 - X1.

This gives you m(X2 - X1) = Y2 - Y1.

Then add Y1 to both sides to get m(X2 - X1) + Y1 = Y2.

This slope would be equivalent to the usual slope formula.

(-2,15)(9,-18)
slope = (-18 - 15) / (9 - (-2) = -33/11 = -3

There can be 2 answers to this question....
point slope form : y - y1 = m(x - x1)

(1) using points (-2,15)...
     y - 15 = -3(x + 2) <== one possible answer

(2) using points (9,-18)
     y + 18 = -3(x - 9) <== another possible answer

Which statement is true?
Ilia_Sergeevich [38]

Answer:

All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.

Step-by-step explanation:

The old math saying: "Every square is a rectangle, but not all rectangles are squares."

What makes a rectangle a rectangle is that it has four right angles.

A square also has four right angles. Therefore, a square is a type of rectangle.

<h3>What makes the other answers wrong:</h3>

A rectangle does not have equal lengths on all four sides like a square does.

A square MUST have four right angles for it to be a square.
