```Lesson 13.6 – Writing
Equations in SlopeIntercept Form
8.F.4 – Construct a function to model a linear
relationship between two quantities. Determine the
rate of change and initial value of the function from a
description of a relationship or from two (x, y) values,
including reading these from a table or from a graph.
Interpret the rate of change and initial value of a linear
function in terms of its graph or a table of values.
Warm-Up
Find the slope of the line.
Today you will learn…
to write an equation of a line in slope-intercept
form.
a. find slope
b. y-intercept
y = mx + b
Extra Example
Write an equation of the line that passes
through the points (0, -1) and (4, -1).
