Best ResponseYou've already chosen the best response.1Find Slope. \[m = \frac{ y2  y1 }{ x2  x1 }\](3, 2) and (5, 8) \[m = \frac{ 8  2 }{ 5 (3) } = \frac{ 82 }{ 5+3 }=\frac{ 6 }{ 2 }=3\]

Best ResponseYou've already chosen the best response.1Now put into PointSlope form. y  y1 = m(x  1) m is slope Substitute x1 and y1 for the given point's coordinates. Slope of 3 (3, 2) y  2 = 3(x  (3)) y  2 = 3(x + 3) Now change into SlopeIntercept form.y = mx + b y  2 = 3(x + 3) Distribute. y  2 = 3x  9 Add 2 to both sides. y = 3x  7
