The points a. (0,5) and f. (10,0) will lie on the given line.

Step-by-step explanation:

The given equation of line is 2x + 4y=20 .

Now, it is required to check whether the given point lie on the line or not. To check it, put the points in the equation of line and if they satisfies, then the point will be on the line else not.

(a) The first point is (0,5). Put this point in the equation as,

$2x + 4y=20\\2\times0+4\times 5=20\\20=20$

Thus, the point satisfies and it will lie on the line.

(b) The first point is (0,10). Put this point in the equation as,

$2x + 4y=20\\2\times0+4\times 10=20\\40\neq20$

Thus, the point doesn't satisfy and hence, it will not lie on the line.

$2x + 4y=20\\2\times1+4\times 4=20\\18 \neq 20$

Thus, the point doesn't satisfy and hence, it will not lie on the line.

(d) The first point is (5,0). Put this point in the equation as,

$2x + 4y=20\\2\times5+4\times 0=20\\10 \neq 20$

Thus, the point doesn't satisfy and hence, it will not lie on the line.

(f) The first point is (10,0). Put this point in the equation as,

$2x + 4y=20\\2\times10+4\times 0=20\\20 =20$

Thus, the point satisfies and it will lie on the line.

Therefore, points (0,5) and (10,0) will lie on the given line.

Answer from: fiorentinologan4

(0,5) and (10,0)

Step-by-step explanation:

The equation of the straight line is given by 2x + 4y = 20 .......... (1)

Now, point (0,5) satisfies the equation (1) as putting x = 0, we will get y = 5.

Now, point (0,10) does not satisfy the equation (1) as putiing x = 0, we get y = 5 ≠ 10

Again, point (1,2) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 2

Now, point (1,4) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 4

Again, point (5,0) does not satisfy the equation (1) as putiing y = 0, we get x = 10 ≠ 5

Finally, point (10,0) satisfies the equation (1) as putiing y = 0, we get x = 10 .

Therefore, only points (0,5) and (10,0) are on the graph of the line 2x + 4y = 20 (Answer)
