2 Section 5.4 – Standard Form of a Linear Equation The Standard Form of a linear equation has both variables on the one side of the equal sign and where A, B, and C are real numbersAx+By=CFirst, how can we graph a linear equation that is in Slope-Intercept? Second, how do we graph for one in Standard Form?
3 Vertical and Horizontal Lines Vertical lines – have the equation x = cHorizontal lines – have the equation y= cyx5-5yx5-5x= -3y= 4x =4y= -2
4 Write two equation equivalent What does it mean to be equivalent?𝑥+4𝑦=3How can we make two equation to be equivalent?
5 Write an equation in Standard Form of the line shown What do we know?What do we need to solve for?2,24,−2
6 Complete an equation in standard form 2,0Ax+4y=6
8 5.5 Write Equation of Parallel and Perpendicular Lines What does it mean to be parallel?What does it mean to be perpendicular?Lets figure it outGet into groups of groups of 4We will be working on the Perpendicular Lines Investigation Worksheet
9 Parallel lines lines that are on the same plane and do not intersect. Two lines are parallel if and only if they have the same slope.
10 Perpendicular Lines lines that intersect to form a right angle. Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. The product of two slopes is equal to -1.
