3.4 Today you will write an equation of a line given two points on the line Solve problems by writing equations. 3.4 Equations of Lines Three forms of a linear equation: Write an equation in point slope form for the line that passes through the points (-2, 4) and (8, 10) Write an equation in slope-intercept form for the line that passes through the points (-2, 4) and (8, 10) Write an equation in slope-intercept form for the line that is parallel to y = 2x - 4 and passes through the point (-3, 7) Write an equation in slope-intercept form for the line that is perpendicular to y = 2x - 4 and passes through the point (-3, 7) Determine whether the lines are parallel, intersect, or coincide. 1. 2. 3. y = 3x + 7 , y= 1 x+5, 3 2y - 4x = 16, y = -3x - 4 6y = -2x + 12 y - 10 = 2(x - 1) Without graphing, determine whether the points (5, 1) (-9, 9) and (7, -1) are collinear.
