SUPPORT Class Learning Target
By the end of the period, I will find the slope or y-intercept from linear equations in slope-intercept form as well as write equations given two or more points.
I will demonstrate this by completing Four-Square Notes and by solving problems in a pair/group activity.

4. Slope-Intercept Form of a Linear Equation
How To Get To Slope-Intercept Form
Notes:
Given
Two
Points x y X1 Y1 X2 Y2
Step 1) Make a table
Use the two points to calculate SLOPE (m)
Y2 – Y1
m =
X2 – X1
Step 2) Plug m and one point into y = mx + b
Solve for b
(Y1) = m(X1) + b
Step 3) Write general formula with m and b
y = mx + b
m = slope
b = y-intercept

6. HW # 26
Write an equation of a line given two points
Y2 – Y1
m =
y = mx + b

HW # 39
Write an equation of the line that represents the linear function represented by the table. x y -4 -2 -1
Step 1) Find Slope
m = -2 – (-1) = -1 = 1
-4 – (-2)
Step 2) Plug Slope and One Point into
y = mx + b
Solve for b
(0) = 1 (0) + b 2
Turn to your partner and share your answer. Please use correct answer.
Partner B, please share what Partner A told you.
b = 0
Step 3) Rewrite general y = mx + b with
m and b
y = 1 x + 0 2
