Answer:
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
Equation:
first we need the slope
So far the equation will look like this
Now to get b just pick one point and insert it into the equation. So I'll just pick (2,3)
when you solve this equation you'll get b
We could also check if we get the same answer if we instead use point (0,-1)
Now we have the equation!
Answer:
The distance between the two points is .
Step-by-step explanation:
We are given two coordinate pairs: (-9, 6) and (-2, 1). We can use the distance formula to solve for the distance between the points.
- The distance formula is
- In coordinates, the pairs are labeled as
Therefore, with this formula, we can just substitute our values into the formula and solve for d.
The distance between the two points is .
Answer: 2.50 dollars
Explanation:
Locate 5 on the x axis, which corresponds to buying 5 kgs of apples.
Draw a vertical line through 5 on the x axis until you reach the blue line. Mark this as point P.
From point P, draw a horizontal line until you reach the y axis. You should arrive at y = 2.5
This tells us that buying x = 5 kgs of apples will cost a total of y = 2.50 dollars.
Answer: She will pay $ 720 for the computer.
Step-by-step explanation:
Since, the cost price of the laptop = $ 900,
Also, after getting the $ 100 gift card,
The new price of the laptop = $ 900 - $ 100 = $ 800
According to the question,
The store is offering 10% off on all computers.
The final price of the laptop = 800 - 10% of 800
= 800 - 80
= $ 720,
Hence, $ 720 will be paid for the laptop.
