The points which are solutions of the equation 6x+7y=19 will be ( 2,1 ) and ( -5, 7 ) so options (B) and (D) will be correct.
What are coordinates?
a pair of numbers used to express the location of a point on a coordinate plane using the horizontal and vertical distinctions from the two reference axes. usually represented by pairs of x-values and y-values (x,y).
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given the equation 6x+7y=19
By substituting
( 0 ,-3 ) ⇒ -21 ≠ 19
( 2 , 1 ) ⇒ 19 = 19 so it is correct.
( 3 , -4 ) ⇒ -10 ≠ 19
( -5 , 7 ) ⇒ 19 = 19 so it is correct.
Hence options (B) and (D) are correct.
