Answer:
-1
Step-by-step explanation:
The slope formula is useful:
m = (y2 -y1)/(x2 -x1)
m = (2 -4)/(0 -(-2)) = -2/2 = -1
The slope of this line is -1.
_____
The points on the line drop 1 unit for each 1 unit to the right.
m = rise/run = -1/1 = -1
Answer:
k= -5
Step-by-step explanation:
When x=1 and y= -2,
x-2y+k=0
1 -2(-2)+ k=0
1+4+k=0
5+k=0
k= -5
Step-by-step explanation:
2 x y + x + 2 y is equal to 3 x y + 2 y final answer is 5xy
5*4 is 20 because 5+5+5+5 is 20
