Question

What are the slope and the y-intercept of the linear function that is represented by the equation y=9x-2?

Answer 1

Answer: (c) The slope is 9, and the y-intercept is -2.

Explanation:

The general slope intercept form of a linear function is as follows:

y = mx + b

where m is the slope and b is the y-intercept. The value m determines steepness and orientation of the line, and value b the vertical shift of the line.

By comparison to the general form we can identify:

the slope (m) is 9

the y-intercept (b) is -2.

Choice (c) reflects correctly this situation.

Answer 2

The answer is b because the slope is 2 and the y intercept is 9
