Identify the slope and y-intercept of the function y = 3x - 6. O A. The slope is 3.
The yintercept is (0, -6).
O B. The slope is 3.
The y-intercept is (0,6).
O C. The slope is 6.
The y intercept is (0, -3).
O D. The slope is 6.
The y-intercept is (0,3).

A. The formula is already in the slope-intercept form, y = mx + b, so you can see that m = 3 and b = -6, which means the slope is 3 and the y-intercept is (0, -6).

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
