Question 1 Show that the points A(1, 2), B(-1, -16) and C(0, -7) lie on the graph of the linear equation: y = 9x - 7.
Solve the following: (a) The locus of a point whose x coordinate is always 7 is the equation. (b) Show that the point (3,1) does not lie on the line 3x + 4y = 16. [4 MARKS]
The point (b,3) lie on the graph of the linear equation 2x-3y+11=0 find b.
