WWhick point lies on the line 2x-y=7?

Question

HELP!?

Answer 1

just plug some numbers for x to get y

the number you plug in and the the number after you plug in is one of the point that lie on that graph

Answer 2

We can rearrange that equation into the y = mx + c format, which is most commonly used for the equations of lines. 2x - y = 7 can become y = 2x - 7. 2x is the gradient and -7 is where it intercepts the y axis. Now that we have the formula in this easier format, we can add some figures into it and see if they land on the line.

Is (3,4) on the line? In this instance, x would be 3 and y would be 4.
y= 2x - 7.
4 = 6 - 7.
Nope, this doesn't make any sense, so (3,4) isn't on the line.

With the formula we can try and find some points too.
y = 2x - 7.
3 = 10 - 7.
x being 5 and y being 3 could satisfy the equation. Therefore (5,3) would be on the line.

Answer 3

You can re arrange the equation to read this : Y=MX+B Where B is the intersecting point of the line on the Y axis, and M is the slope of the line. so your equation would read Y=2X-7. Thus (0,-7) is a point on that line, you can also follow your slope up and down the line to get more answers. It's amazing that I still remember that from highschool.

Answer 4

A point (x,y) lies on the line 2x-y=7 if its coordinates make the equation true. Because you didn't specify any points, I can only suggest plugging your coordinates into the equation.

Answer 5

To find the point just substitute some points to satisfy the given equation such as ( 5 , 3 ) or ( 2 , - 3 ) or ( - 2 , - 11) etc.

Answer 6

I m a bit rusty , for I haven t done any math in about 8 years. Yet I believe the answer is x = 3.5y or x = 3.5 + y.
