    • Lesson 3­1.notebook September 23, 2013 Assignment: 1­­>L3.1, pg. 157 ­ 158, #7 ­ 11 all & #24 ­ 34 evens ­ Due Tomorrow (9/24)
    • Lesson 3­1.notebook September 23, 2013 Lesson 3.1 WarmUp: Translate the sentence into an equation. 1) The quotient of 25 and t plus 6 is the same as twice t  plus 1. Translate the equation into a sentence. 2) 3(g + 8) = 4h ­ 10 Solve the equation.  Show all steps. 3)   ­1/5  ­  4/9x  =  2/15 4) Find the sum of 3 consecutive odd integers if the sum  of the first 2 integers is equal to 24 less than four times the  third integer. Write an equation involving absolute value for the graph. 5) ­7 ­6 ­5 ­4­3 ­2 ­1 2 30 1

    • Lesson 3­1.notebook September 23, 2013 Lesson 3.1: *linear equation ­ an equation that forms a line when it is graphed *standard form ­ a linear equation that is written in the form: Ax  +  By  =  C *x­intercept ­ the x­coordinate of the point at which the graph of an equation  intersects the x­axis *y­intercept ­ the y­coordinate of the point at which the graph of an equation  intersects the y­axis variable terms constant
    • Lesson 3­1.notebook September 23, 2013 *FYI: To find the x­intercept: ...plug in zero for y ­ and solve for x! To find the y­intercept: ...plug in zero for x ­ and solve for y! To graph a linear equation... ­­find the x and y intercepts ­­make a table of values
    • Lesson 3­1.notebook September 23, 2013 Lesson 3.1 examples: Graph the following by finding the x and y intercepts. A) 2x  +  4y  =  16 X Y
    • Lesson 3­1.notebook September 23, 2013 X YB) ­x  +  2y  =  3
    • Lesson 3­1.notebook September 23, 2013 Graph the following by making a table. C) y = 2x  ­ 3 X Y
    • Lesson 3­1.notebook September 23, 2013 D) x  =  3 X Y
    • Lesson 3­1.notebook September 23, 2013 X Y E) y  =  ­2
    • Lesson 3­1.notebook September 23, 2013 F) x  +  2y  =  4 X Y
