Lesson-3.1.5- Interpret and obtain the equation of a straight-line graph. Questions may: ??? use and request lines in different forms, e.g. ax + by = c y = mx + c x = k ??? involve finding the equation when the graph is given ??? ask for the gradient or y-intercept of a graph from an equation, e.g. find the gradient and y-intercept of the graph with equation 5x + 4y = 8. Candidates are expected to give equations of a line in a fully simplified form.PreviousLesson-3.1.7- Find the gradient and equation of a straight line perpendicular to a given line. Examples include: ??? Find the gradient of a line perpendicular to 2y = 3x + 1 . ??? Find the equation of the perpendicular bisector of the line joining the points (???3, 8) and (9, ???2).Next
