Slope-Intercept Form 12.1b

Objectives Given two points I can write a linear equation I can graph a linear equation in slope-int form

Write the equation graph the equation

Last class…

Slope Intercept Form of a Linear Equation y-intercept

Writing an Equation from a Graph Step 1 Find y-intercept Step 2 Find slope (rise over run) (change in y over change in x) Step 3 Put values in y-intercept form (y=mx+b) y-intercept= Slope=

Now let’s do the same thing… But without the graph…

Write the equation

What can we do with two points? Let’s say we have two points (3,1) (4,3) x₁ y₁ x₂ y₂ y-intercept Slope

Writing Equations from Two Points What’s the equation of the line that passes through (2,1), (5,-8) ? x₁ y₁ x₂ y₂ y-intercept= Slope=

Writing Equations from Two Points What’s the equation of the line that passes through (3,-2), (1,-3) ? x₁ y₁ x₂ y₂ y-intercept= Slope=

Writing Equations from Two Points What’s the equation of the line that passes through (1,-6), (-3,10) ? x₁ y₁ x₂ y₂ y-intercept= Slope=

Writing Equations from Two Points What’s the equation of the line that passes through (-3,4), (2,-1) ? x₁ y₁ x₂ y₂ y-intercept= Slope=

Review Given two points I can write a linear equation I can graph a linear equation in slope-int form
