Q:

50 POINTS AND BRAINIEST PLEASE HELPWhich equation does the graph below represent?y = βˆ’2x y = - 1/2x y = 2x y = 1/2x

Accepted Solution

A:
Answer:y = -2xStep-by-step explanation:If you notice very carefully then you will see that the line passes through the points :( 1 , - 2 )( - 1 , 2 )Hence the value of x = 1 when the value of y = - 2 .We know that - 2 × 1 = - 2⇒ - 2 x = y⇒ y = - 2xHence the first OPTION is correct .Verification :For points ( - 1 , 2 ) we can write :y = - 2x⇒ 2 = - 2 × - 1⇒ 2 = 2Hence the answer is verified .Always try to use the converse of the graphical method .( Nothing converse is there ... just saying the opposite steps of that method :P )I mean in graphical method we plot points and then join , here identify the joined points and then make the equation .
