What are the x- and y-intercepts of the graph defined by the equation y = − 3 x + 15 ?

all of them.

step-by-step explanation:

every month has 28 days. some just continue on after reaching 28.

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)
