Answer:A, 1/1000
Step-by-step explanation:
10 times -10 is -100. -100 times -10 is 1,000
8 1/9 because 9 times 8 is 72 and 73-72=1 so 8 1/9
The lines that Mark drew are perpendicular.
Answer:
D
Step-by-step explanation:
y_2 - y_1 / x_2 - x _1
4 - 2 / 3 - (-1) = 2/4 = 1/2
y +4 = 1/2 (x + 3) distributive property
y + 4 = 1/2x + 1.5
y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)
therefore your equation is y = 1/2x - 5/2
