1) Find slope. \[Slope = \frac{ y2  y1 }{ x2  x1 }\]\[Slope = \frac{ 1  1 }{ 5  4 } = \frac{ 2 }{ 1 } = 2\] So you have a slope of 2. You also have a given point. 2) Put into PointSlope form. \[y  y1 = m(x  x1) \] Lets use point (4, 1) and the slope of 2. \[y  1 = 2(x  4)\]3) Change into SlopeIntercept form. \[y  1 = 2(x  4)\]Distribute.\[y  1 = 2x + 8\]Add 1 to both sides.\[y = 2x + 9\] Slopeintercept form is: \[y = 2x + 9\]
