MS Algebra A-F-IF-7 – Ch. 5.6aGraph Using Slope-Intercept Form
Mr. Deyo
Graph Using Slope-Intercept Form
By the end of the period, I will apply the slope-intercept form and graph linear equations.
I will demonstrate this by completing Four-Square Notes and by solving problems in a pair/group activity.

Notes: How To Get To Slope-Intercept Form
Ax + By = C-Ax -Ax
By = -Ax + C
B B B
y = (-A/B)x + C/B
y = mx + b
A = Coefficient of xB = Coefficient of yC = Constant

for y
Slope-Intercept Form of a Linear Equation
m = slopeb = y-intercept
Solve
for y
Problem(s) A Identify slope and y-intercept
Identify the slope and y-intercept of the line with the given equations.
y = 5x - 3 3x - 3y = 12
Problem(s) A Identify slope and y-intercept
Identify the slope and y-intercept of the line with the given equations.
SOLUTION
y = 5x - 3
The equation is in the form
y = mx + b. So, the slope
(m) of the line is 5, and the
y-intercept is -3.
3x - 3y = 12You have to rewrite the equation in slope-intercept form by solving for y.
3x - 3y = 12-3x -3x
-3y = -3x + 12-3 -3 -3
y = 1x - 4So, the slope (m) of the line is
1, and the y-intercept is -4.
Problem(s) B Identify slope and y-intercept
Identify the slope and y-intercept of the line with the given equations.
y = 3x + 4 3x + y = 2
Problem(s) B Identify slope and y-intercept
Identify the slope and y-intercept of the line with the given equations.
SOLUTION
y = 3x + 4
The equation is in the form
y = mx + b. So, the slope
(m) of the line is 3, and the
y-intercept is 4.
3x + y = 2You have to rewrite the equation in slope-intercept form by solving for y.
3x + y = 2-3x -3x
y = -3x + 2So, the slope (m) of the line is
-3, and the y-intercept is 2.
