Answer:
y = 3x - 1
The slope intercept is -1.
To find the slope, do the formula (y sub2 minus y sub1)/(x sub2 minus x sub1) then reduce.
(14 - (-10))(5 - (-3)) = 24/8
24/8 = 3
Answer: 240 km
Step-by-step explanation:
From the graph :
50 miles = 80km
1 miles = 80/50 km
Therefore :
150 miles = 80/50 x 150
150 miles = 240 km
Answer:
The answer is (7,-19)
Step-by-step explanation:
Remember, 18 is x, and -10 is y. The rule says to subtract 11 from 18, which would be 7. For y, you add -9 to -10, which would be -19.
Therefore, your answer should be (7,-19)
Hope this helps!

5 is the side of the pentagon
Answer: One face is 16 square centimeters.
Step-by-step explanation: To find the area of a face, you need to know the length of the side. All the sides of the cube are the same, so take the cube root of 64.
cm is the length of the side
The area of one face is the side length squared 4² = 16
4cm × 4cm = 16 square centimeters.
