Equations of Perpendicular Lines

Equations of Perpendicular Lines

9-1 GCSE lesson. Explains perpendicular thorough diagrams and then through algebra. Includes questions examining the gradient of perpendicular lines and questions finding perpendicular lines through a specific point.

Equation of Perpendicular Line

Equation of Perpendicular Line

Two graphs per grid to investigate the perpendicular equation of a line. 6 grids in total on the worksheet. Students are able to deduce the relationship between the equation of a line and the equation of the line perpendicular to it. Very useful to get students to investigate and explore and be independent learners. I have also included the smart notebook file to go with it, 1 graph per slide to project on the board and or edit. There are also a few other slides I added such as success criteria and old NC levels.

Straight Line Loop Cards

Straight Line Loop Cards

Loop cards, read out gradient and y intercept, the person with this graph will have to say what the equation of their line is then in turn read out the description of the next graph. Can be starter or plenary activity

Equations of Parallel Lines

Equations of Parallel Lines

GCSE 9-1 Higher lesson: Recaps y=mx+c and looks at finding parallel lines, rearranging equations into y=mx+c, fining equations of parallel lines through a fixed point.

Slope-Intercept Form Graphing Art

Slope-Intercept Form Graphing Art

This activity allows students to practice graphing using slope-intercept form. Students are given equations in slope-intercept form and graph the lines with the given end points. In doing so, students create a picture, and will also find the area of their picture and color accordingly. This is a great activity to connect graphing, area, and art. This activity is perfect to reinforce graphing equations. Students are engaged as they create their picture. Graphing Art is perfect for students who finish early or who want an extra challenge. This No Prep product is also a great activity for a substitute. Use this product as homework, in-class activity, or extra credit to review and reinforce graphing with slope-intercept form. Included in this product are the graphing instructions, a blank graph, and the solution.

Identifying basic straight line graphs

Identifying basic straight line graphs

20 slides of lines such as y=4 x=3 y=-x, y=x and then a few x +y = 5 etc. Used with mini whiteboards as a reminder of lines and to reinforce the basics and then to introduce the movement of graphs up and down the y axis. I used it with a bottom set year 9, good for AFL
