Question

Find three solutions of the equation. y=2x-6

A) (-2,-10), (1,-4), (2,-1)
B) (-2,-10),(1,-4), (0,-6)
C) (0,-6), (3,-2), (-2,-10)
D) (1,-4),), (0,-6), (-1,-9)

Answer 1

B

Explanation:

put the values of x and y into the equation respectively.

if LHS =RHS then it is a solution

e.g put (-2,-10) into the equation

-10=2(-2)-6

-10=-10

hence is a solution .

or put x value into the equation such as

(-2,-10)

y=2(-2)-6

the ans should be y=-10.As u can see is equal to the solution given.Hence is a solution.
