3. How to move to the next point up (+) or down (-) right Y-Intercept or where you begin

4.  4x + 3y + 12 = 0 solve for y  3y = -4x – 12  y = -4x – 4 3 Start at -4 Move down 4 And right 3

5.  4x + 3y + 12 = 0 solve for y  3y = -4x – 12  y = -4x – 4 3 Create a T-chart Choose values for x that Make it easy, 0 and a multiple of the denominator XY 0-4 -30

6. m=b= 4 The goal is always to fill in the m and the b! y = mx+b y = x+ 4

7. m=and it goes through (3, 1) x y The goal is always to fill in the m and the b! y = mx+b 1 = (3) + b 1 = -2 + b 3 = b y = x + 3

8. it goes through (1, 3) and (2, 8) x 1 y 1 x 2 y 2 The goal is always to fill in the m and the b! y = mx+b 3 = 5(1) + b 3 = 5 + b -2 = b y = 5x - 2

9. it goes through (1, 3) and is parallel to y = 2x + 4 x 1 y 1 The goal is always to fill in the m and the b! Parallel lines have equal slopes So m=2 y = mx+b 3 = 2(1) + b 3 = 2 + b 1 = b y = 2x + 1

10. it goes through (2, 3) and is perpendicular to y = 2x + 4 x 1 y 1 The goal is always to fill in the m and the b! perpendicular lines have opposite reciprocal slopes so m= y = mx+b 3 = (2) + b 3 = -1 + b 4 = b y = x + 4
