A set of ordered pairs where each first element is paired with one and only one second element and no element in either pair is without a partner.

Step-by-step explanation:

Question 1: Calculate the slope, x-intercept and y-intercept of a linear equation, f (x) = 5x + 4?

Solution:

Given,

f (x) = 5x + 4

The general form of a linear equation is,

f (x) = mx + c

So,

Slope = m = 5

Substitute f (x) = 0,

0 = 5x + 4

5x = - 4

x = - 45

The x-intercept is (-45, 0)

Substitute x = 0,

f (x) = 5 (0) + 4

f (x) = 0 + 4

f (x) = 4

The y-intercept is (0,4)
