Question 59674: For the equation y = 2x-4, select all that are true.
y = 2x - 4 is a linear equation
(1, 2) is a solution to the equation
(1, -2) is a solution to the equation
(-1,-6) is a solution to the equation
(2, 0) is a point on the graph of y = 2x – 4
(2, 0) is on the line y = 2x – 4

y=2x-4 is a linear equation.
when we input the values x=1 and y=2 in the given equation,
we have 2=2-4
2=-2, which is not correct
so (1,2) is not a solution for the given equation.
when we put the values x=1 and y=-2,
we have, -2=-2, which is correct
so (1,-2) is a solution.
when we input the values x=-1 and y=-6 in the given equation,
we have, -6=-6, which is correct
so (-1,-6) is a solution.
now put the values x=2and y=0,
we have,0=0.
that means (2,0) is a solution of the given equation, y=2x-4.
That is (2,0) lies in the graph of the equation, y=2x-4.
The point (2,0) lies in the line y=2x-4(because,y=2x-4 is linear equation so its graph is a straight line.
