Question

show that points(1,2)(0-7)(-1,-16) lie on thw graph of the equation 9x-y=7​

Answer 1

Answer:

Yes

Step-by-step explanation:

Given there are three points such that,

• (1,2)
• (0,-7)
• (-1,-16)

Also, given there is line having equation

• 9x - y = 7

To show that, these points lie on the given line.

We know that, if a point lies on the given line, then it will satisfy that given equation for the line.

So, Let's check the points.

(1,2)

L.H.S

= 9(1) - 2

= 9 - 2

= 7

= R.H.S

Thus, L.H.S = R.H.S

Hence, it lies on the given line.

(0,-7)

L.H.S

= 9(0) - (-7)

= 0 + 7

= 7

= R.H.S

Thus, L.H.S = R.H.S

Hence, it lies on the given line.

(-1,-16)

L.H.S

= 9(-1) - (-16)

= -9 + 16

= 7

= R.H.S

Thus, L.H.S = R.H.S

Hence, it lies on the given line.
