Slope-Intercept Form 12.1b
5
Objectives Given two points I can write a linear equation I can graph a linear equation in slope-int form
6
Write the equation graph the equation
7
Last class…
8
Slope Intercept Form of a Linear Equation
y-intercept
9
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=
10
Now let’s do the same thing…
But without the graph…
11
Write the equation
12
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
13
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=
14
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=
16
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=
17
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=
18
Review Given two points I can write a linear equation
I can graph a linear equation in slope-int form
19
