Writing Equations in Point-Slope Form

To learn about quadratic equations

To understand the properties of circles

To solve complex integrals

To write equations of lines using a point and a slope in point-slope form

A constant value

The y-intercept

The x-intercept

The slope of the line

From the slope formula

From the distance formula

From the quadratic formula

From the Pythagorean theorem

Find the y-intercept

Graph the line

Identify the coordinates of the point and the slope

Convert to slope-intercept form

y + 4 = 1/4(x - 3)

y - 4 = -1/4(x + 3)

y + 4 = -1/4(x - 3)

y - 4 = 1/4(x + 3)

-7/3

7/3

-3/7

3/7

Choose one of the points to use in the equation

Find the y-intercept

Convert to standard form

Graph the points

y + 2 = 4(x - 1)

y - 6 = 4(x - 3)

y - 2 = 4(x + 1)

y + 6 = 4(x + 3)

y = -1/2x - 3.5

y = -1/2x + 3.5

y = -1/2x - 7

y = -1/2x + 7

y = 4x - 3

y = 4x + 3

y = -4x - 3

y = -4x + 3
