Divide each term separately\[\frac{ 3x + 9 }{ 3 }\]\[\frac{ 3x }{ 3 } = x\]\[\frac{ 9 }{ 3 } = 3\] x + 3

2) PointSlope form. y  y1 = m(x  x1) Find slope. (2, 3) and (2, 7) \[m =\frac{ y2  y1 }{ x2  x1 }\]\[m = \frac{ 7  3 }{ 2 (2) } = \frac{ 7  3 }{ 2 + 2 } = \frac{ 4 }{ 4 } = 1\]Slope(m): 1 Point: (2, 3) y  3 = 1(x  (2)) y  3 = 1(x + 2) Change to Slopeintercept form. y = mx + b Distribute. y  3 = x + 2 Add 3. y = x + 5 Change to standard form. Ax + By = C 'A' cannot be a negative or a fraction. y = x + 5 Subtract x from both sides. x + y = 5 Multiply everything by 1. \[1(x + y = 5)\] x  y = 5 < Your answer. (:
