Question

1. Which of the following lines passes through (1, 2):
(a)x+y= 3 (b) x - y = 1 (c)x= 2
(d)x= 1​

Answer 1

Answer:

Step-by-step explanation:

where you can, rewrite each of the equations in the form y = mx + b

(a)    y = -x + 3

(b)    y = x

(c)    x = 2

(d)    x - 1

See the graph, only the equation (a) x + y = 3 passes through the point (1,2).
