The slope-intercept equation for a line is y = mx + b where m is the slope and b is the y-intercept of the line. From the graph, you can see that the y-intercept (the y-value from the point where the line crosses the y-axis) is -4. 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, -9) and (2, 1) so the slope becomes:

Plugging these values into the slope-intercept equation:

y = 2\(\frac{1}{2}\)x - 4

The first step to solve a quadratic expression that's not set to zero is to solve the equation so that it is set to zero:

x² - 6x + 25 = 5x - 5
x² - 6x + 25 + 5 = 5x
x² - 6x - 5x + 30 = 0
x² - 11x + 30 = 0

Next, factor the quadratic equation:

x² - 11x + 30 = 0
(x - 5)(x - 6) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (x - 5) or (x - 6) must equal zero:

If (x - 5) = 0, x must equal 5
If (x - 6) = 0, x must equal 6

So the solution is that x = 5 or 6

The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 24° - 22° = 134°

The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)² : a = π r².

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).
