Answer:
Q1 = c, Q3= b, Q4 = a
Explanation:
Q1
Natural numbers are positive counting numbers. Eg: 1,2,3 etc. It is not a) or b) as it can be both even and odd. Real numbers are all numbers which includes negative numbers. So the answer has to be c) Composite numbers
Q3
The question says the point lies on the x axis which means the y value has to be 0. This leaves us with two options - a) or b). But as the question mentions the negative side of the x axis, the x value should be negative number. So the answer is b) (-10,0)
Q4
We just label the coordinate (a, 1) as (x, y) and substitute into the equation
3x - 2y + 4 = 0
a = x 1 = y
3a - 2(1) + 4 = 0
3a - 2 + 4 = 0
3a + 2 = 0
3a = -2
a = -2/3
So the answer is a) -2/3
