The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -7) and (2, 5) so the slope becomes:

A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.

A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.

7x - 4 < -8 - 3x
7x < -8 - 3x + 4
7x + 3x < -8 + 4
10x < -4
x < \( \frac{-4}{10} \)
x < -\(\frac{2}{5}\)

According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:

c² = a² + b²
c² = 3² + 9²
c² = 9 + 81
c² = 90
c = \( \sqrt{90} \)
