Unformatted text preview: PointSlope Form of the Equation of a Line: y  y 1 = m(x  x 1 ) Given a point (x 1 ,y 1 ) and the slope m on a line. SlopeIntercept Form : y = mx + b ; m = slope and b = yintercept Standard Form : Ax + By = C , where A, B , and C are real numbers and A and B are not both zero. (X1,Y1) (X2, Y2) rise = y2  y1 run = x2  x1 Ex. 1: Given a line containing the point (1, 3) and slope = 2/5, find the equation of the line in slopeintercept form, then graph the line. Ex. 2: Write the equation of the line containing the points (2, 2) and (1, 4). Express your answer in pointslope form and standard form. Ex. 3: Write the equation of the line given the following properties. a) slope undefined through point (3, 5). b) horizontal line through point (2, 4). Ex. 4: Find slope and yintercept of 4x + 5y = 10, then graph the line....
