1. Writing equations given a point and the slope of a line

2. Solve for b
4 = -2 ∙ 3 + b
4 = -6 + b +6 +6
10 = b

3. Solve for b
-8 = (-2)(-11) + b
-8 = 22 + b
-22
-22
-30 = b

4. Y = mX + b -3 = (-2)(6) + b -3 = -12 + b +12 +12 9 = b Y = -2X + 9
Write the equation of the line that goes through point (6, -3) and has a slope of -2 m x y
Y = mX + b
-3 = (-2)(6) + b
-3 = b
+12
+12
9 = b
Y = -2X + 9

5. Y = mX + b -7 = (⅔)(6) + b -7 = 4+ b -4 -4 -11 = b Y = ⅔X - 11
Write the equation of the line that goes through point (6, -7) and has a slope of ⅔ m x y
Y = mX + b
-7 = (⅔)(6) + b
-7 = 4+ b -4 -4
-11 = b
Y = ⅔X - 11

6. Y = mX + b 9 = (2)(2) + b 9 = 4 + b -4 -4 5 = b Y = 2X + 5 m x y
Write the equation of the line that goes through point (2, 9) and is parallel to the line Y = 2X + 3 m x y
Y = mX + b
9 = (2)(2) + b
9 = b -4 -4
5 = b
Y = 2X + 5
