In the equation, y=3x+2, is the point (2,8) a solution the equation?

1: Yes, the point is solution
2: No, the point is not a solution

Sagot :

Answer:

Given: The equation of the line y = 3x+2

The condition for a point to be on a line is to satisfy its equation

(i) Let us consider (1/3, 3), substitute x = 1/3 and y = 3 in given equation

3 = 3(1/3) + 2

= 1 + 2

= 3

Hence, (1/3, 3) lies on the line

(ii) Let us consider (2, 8) and substitute x = 2 and y = 8 in given equation

8 = 3(2) + 2

= 6 + 2

= 8

Hence, (2, 8) lies on the line

(iii) Let us consider (0, 2) and substitute x = 0 and y = 2 in given equation

2 = 3(0) + 2 = 2

  • Hence, (0, 2) lies on the line

(iv) Let us consider (7, 19) and substitute x = 7 and y = 19 in given equation

19 = 3(7) + 2

= 21+ 2

= 23 ≠ 19

  • hence, (7,19) doesn’t lie on the line

• Therefore ,Yes the point is a solution .

Step-by-step explanation:

Hope this helps you XD ✌️

Carry on learning !!

Yes, the point is a solution
The point (2,8) means that whenever x=2, the y=8.
If you substitute x=2, then y=3(2)+2=8!
