What is the y-intercept of the line defined by
y = 6x - 4

The power of the input variable, x, of the function is 1, therefore, the

function is a linear function.

Correct response:

The function defining the line is; y = 6·x - 4

The function is a linear equation of the form; y = m·x + c

Where;

m = The slope

c = The y-intercept

By comparison, we have;

The y-intercept can also be obtained as follows;

The y-intercept is the value of the function when x = 0

Therefore;

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
