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.
