Question

Show that the points (2, 1), (11, 2) and (20, 3) are
the solutions of the linear equation x = 9y – 7.

Answer 1

Answer:

As explained below

Step-by-step explanation:

if a point is solution to the equation then putting the points in x,y value will solve the equations

x=9y-7

take points (2,1)

2=9-7=2 so lhs=rhs hence (2,1) is solution to the equation

point (11,2)

11=9(2)-7= 18-7=11

so lhs=rhs hence (11,2) is solution to the equation

point (20,3)

20=9(3)-7=20 hence (20,3) is solution to the equation
