Understanding Linear Equations

The y-intercept of the line

The x-intercept of the line

The midpoint of the line

The slope of the line

It requires knowing the slope of the line

It requires knowing the exact y-intercept

It requires knowing two points on the line

It requires knowing the x-intercept

The x-intercept

The y-intercept

The slope and one point on the line

Two points on the line

By adding the x and y coordinates

By multiplying the x-coordinates

By dividing the difference in y-coordinates by the difference in x-coordinates

By dividing the difference in x-coordinates by the difference in y-coordinates

A line with a known y-intercept

A line with a known slope and a point

A line with two known points

A line with a known x-intercept

y = 3/5x - 4

y = 3/5x + 3

y + 3 = 3/5(x + 4)

y - 3 = 3/5(x - 4)

Multiply the slope by the x-coordinate

Set x to zero and solve for y

Divide the y-coordinate by the slope

Set y to zero and solve for x

y = 2/3x - 5/3

y = -2/3x - 5/3

y = 2/3x + 5/3

y = -2/3x + 5/3

By converting one form to the other

By calculating the area under the line

By finding the x-intercept

By using the midpoint formula

The slope-intercept form

The point-slope form

The two-point form

The quadratic form
