Equations of linear graphs — practice question
The sketch presents a line L together with points A and B on a grid. Both axes are labelled, and A lies on the line to the left of the y-axis, while B is on the line at about (6,1).
(a)[1]
Write down point A's coordinates.
(b(i))[1]
Find the gradient of line L.
(b(ii))[2]
Write down the equation for line L in the form $y = mx + c$.
(c(i))[1]
Draw a line that is perpendicular to line L and goes through point A.
(c(ii))[1]
Mark point C on the grid and write down point C's coordinates.
(c(iii))[2]
Find the perimeter of triangle $ABC$ by measuring.
