Straight Line
A straight line is shown with the x and y axis intercepts shown. A point P is marked on the line but the coordinates are not given. P is then joined back to the origin, splitting the triangle into two parts. The challenge is to find the area of...
Straight line and circle
In this resource students are challenged to determine the equation of the line that goes through a given coordinate point and is also tangential to a circle centred on the origin. The final step is to determine the radius of the circle.
The solution involves determining the gradient of the tangent and also...
Straight Line Graphs
This MEP resource from CIMT is taken from text book 8B which covers the mathematics scheme of work for the second half of year 8.
Straight line graphs covers: coordinates, plotting points on straight lines, plotting graphs given their equations, the equation of a straight line and the equation of a line...
Straight Line Graphs
This resource contains seven problems requiring students to think, explore, explain and justify the mathematics they use in order to solve the problems presented. Students will explore the equations of straight lines, parallel lines, perpendicular lines, equations of straight lines in a variety of forms and to find...
Straight Line Graphs Mystery
This resource created by Shirley Fall has twenty mystery fact cards, each containing a statement about the features of straight line graphs and how they lie on a 3 by 3 grid. The rationale is for students to use the fact cards to discover the features of each graph - its gradient, its intercept, its graph and...
Straight Lines: Y = mX + c
This interactive excel program is about finding the equation of straight lines in the form ax+by+c=0. The first two sheets deals with the equation of the line through two given points and the equation of the line through a point perpendicular to a given line. The...
Straight-line Graphs
This video resource from Teachers TV is presented by Fran and Dave, who demonstrate practical applications of mathematics as they investigate how straight line graphs can be used to compare the price difference of two mobile phone deals.
Formulae are developed and graphs drawn to show how the cost of '...
Straight-Line Graphs
This video resource from Teachers TV features mathematics teacher Kathryn Hurrell as she delivers a lesson on straight line graphs to a lower ability Year Nine class at Comberton Village College. Using a set of axis drawn on the floor of the classroom, practical activities help students to understand the concepts...
