Yes it is because you replace the 2 for the x and the 5 for the y.
2+5=7
7=7
2(2)-3(5)=-11
4-15=11
-11=-11

What is the slope of the line passing through the points (−1, 3) and (4, −7) ?

alexira [117]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

in this problem we have

$A(-1,3)\ B(4,-7)$

substitute in the formula

$m=\frac{-7-3}{4+1}$

$m=\frac{-10}{5}$

$m=-2$

therefore

<u>the answer is the option A</u>

$m=-2$

Joey Chestnut is trying to break his own record for eating the most whole hot dogs in 101010 minutes. He needs to eat more than

anygoal [31]

Answer:

$9d+11\frac{1}{4}>72$

Step-by-step explanation:

We are supposed to write an inequality to determine the number of hot dogs per minute Joey must eat for the last 9 minutes to break his record.

Let d represent the number of hot dogs Joey eats per minute for the next 9 minutes.

We have been given that after 1 minute, Joey has eaten $11\frac{1}{4}$ hot dogs.

Hot dogs eaten in next 9 minutes would be 9 times d that is $9d$ .

Total hot dogs eaten by Joey would be hot dogs eaten in 1 minute plus next 9 minutes: $9d+11\frac{1}{4}$ .

Since to break the record Joey needs to eat more than 72 hot dogs. We can represent this information in an inequality as:

$9d+11\frac{1}{4}>72$

Therefore, our required inequality would be $9d+11\frac{1}{4}>72$ .

On a coordinate plane, points (2, 4), (4, 8), and (5, 10) are plotted.

mario62 [17]

Step-by-step explanation:

(2, 4), (4, 8) and (5, 10) are on the line y = 2x.

Hence they line on a straight line,

The line passes through the origin, and

it shows a proportional relationship.
