Writing Linear Equations Notes

4. Warm-Up
Identify the slope and y-intercept of the following linear functions:
f(x) = 3x – 1
r(x) = 2 – x
y(x) = 1/3 x

5. Great Wall of China, Huairou, China

6. Learning Intention/Success Criteria
LI: We are learning how to write equations using a point and a slope SC: I know how to 1. substitute numbers into equations 2. use the order of operations to solve 3. write equations in slope intercept form 4. identify m, x, y, and b values 5. solve multi step equations for a variable

7. Today’s Vocabulary Slope
A number which is used to indicate the steepness of a line
Indicates if the line is tilted uphill or downhill
Indicated by the letter “m”
Point
The pair of numbers giving the location on the coordinate plane
Written in the form: (x, y)

8. Today’s Vocabulary Y-Intercept
The point at which the function crosses the y-axis
Indicated by the letter “b”
Slope Intercept Form
A way of writing an equation with a slope and y-intercept
Written: f(x) = mx + b

9. Example 1: Use slope-intercept form to write a linear equation m = 3 f(-1) = 2
y = mx + b
SC4
m: x: y: 3 -1 2
SC1
2 = (3)(-1) + b
SC2 SC5
2 = -3 + b
+ 3
+ 3
_____________
5 = b
SC1 SC3
y = 3x + 5 x y

10. Guided Practice 1
Use slope-intercept form to write a linear equation g(x) has a slope of -4 and g(-1) = 3 A] g(x) = -4x – 1
B] g(x) = -4x + 3
C] g(x) = -4x + 1
D] g(x) = -4x – 3

11. Guided Practice 1
Use slope-intercept form to write a linear equation g(x) has a slope of -4 and g(-1) = 3
g(x) = mx + b
3 = (-4)(-1) + b
3 = 4 + b
g(x) = -4x – 1 -4
_____________ -4
-1 = b

12. Guided Practice 2
Use slope-intercept form to write a linear equation h(x) has a slope of ½ and goes through (2, 3) A] h(x) = ½ x + 2
B] h(x) = ½ x + 3
C] h(x) = ½ x + ½
D] h(x) = ½ x

13. Guided Practice 1
Use slope-intercept form to write a linear equation h(x) has a slope of ½ and goes through (2, 3)
h(x) = mx + b
3 = ( ½ )(2) + b
3 = 1 + b
h(x) = ½ x + 2 -1 -1
_____________
2 = b
