1. The set of ordered pairs that defines a function is: C. {(1, 2), (2, 6), (3, -2), (4, -6)}

2. C. y =x^2 - 3 is not a linear function.

3.  The value of the function f(x) = 3/5 x + 4 when x=10 is: B. 10

4. The slope of  y = 4x + 3 is: 4.

5. The y-intercept of y=3/4 x+11 is: 11.

What is a Linear Function?

  • A linear function is a type of relation whereby every x-value has only one possible corresponding y-value.
  • Where m is the slope, and b is the y-intercept, a linear function can be modelled as y = mx + b.

1. The set of ordered pairs, {(1, 2), (2, 6), (3, -2), (4, -6)} has exactly one y-value that corresponds to each x-value. Therefore, the set of ordered pairs that defines a function is: C. {(1, 2), (2, 6), (3, -2), (4, -6)}

2. C. y = x^2 - 3 is not a linear function.

3. Given, y = 3/5 x + 4, to find the value when x = 10, substitute x for 10 into the equation.

Thus:

y = 3/5(10) + 4

y = 6 + 4

y = 10

4. The slope of  y = 4x + 3 is: 4.

5. The y-intercept of y =3/4 x+11 is: 11.
