Question

18. The graph of linear equation x+2y = 2, cuts the y-axis at:

2 points

a. (2,0)

b. (0,2)

c. (0,1)

d. (1,1)

​

Answer 1

(b) (0,2)

Step-by-step explanation:

if it cuts at y axis, then x coordinate is 0,

so the coordinates are

(0,2)

Answer 2

Answer:

x coordinate of every point on the
y-axis is ZERO.
Therefore, out point must be something like (0, y)
Options (a) and (d) state otherwise, hence, we "eliminate" them.
Now, our work is to choose between the leftovers, I.e., options (b) and (c) which can be only done by getting the exact value of y at which the line x + 2y= 2 cuts the y-axis.

Put x = 0
==> 0 + 2y = 2
==> 2y = 2
==> y = 1
Hence, the point at which the line (x+ 2y =2) cuts the y-axis is (0,1).
Option (c) has our right answer, so we choose option (c) as "our" right answer.
