f(x) = a(b)^x

• a: y-intercept

• b: base or common ratio

f(x) = 5(2)^x

• y-intercept: (0,5)

• base/common ratio: 2

Writing linear equations

When writing linear equations, we want to use slope-intercept form (y=mx+b). There are different ways to do this depending on the information we are given.

Write a linear equation using points

• First find the slope

• Now pick one of those points

• Plug the slope (m) and the point (x₁, y₁) into the point-slope equation y-y₁=m(x-x₁)

• Simplify and reduce until you have the equation in slope-intercept form (y=mx+b)

Write a linear equation using a table

• pick two points from the table

• calculate the slope

• pick one point from the table

• plug in your slope and your point into the point-slope equation y-y₁=m(x-x₁) then simplify and reduce until the equation is in slope-intercept form (y=mx+b)

• If the y-intercept is included in the table, you can skip this step and just plug your slope and intercept into y=mx+b
