Find the slope between the two points: (3,-2) and (4,7)

Answers

Answer 1
Answer:

The slope between the two points (3,-2) and (4,7) is 9.

What is slope of a line?

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

To find slope given two(x1, y1) and(x2, y2) points, we use the formula

m=(y_2-y_1)/(x_2-x_1)

Given coordinates are:(3,-2) and (4,7)

x1= 3, x2= 4 , y1= -2 and y2= 7

Using Formula,

m=(7-(-2)))/((4-3))

   = 9 /1

   = 9

So, the slope between two points is 9.

Answer 2
Answer: To find slope given two points, there is a formula you can use: (y2-y1)/(x2-x1). Y2 stands for the second y coordinate and y1 stands for the first y coordinate. The same logic applies to the x's. Let's assume that (3, -2) is x1, y1 and (4,7) is x2, y2. Let's plug them into the formula.

(7-(-2))/(4-3).
7-(-2)=9 for total y value.

4-3=1 for the x value.

Now we divide them.
9/1=9. 9=m. M is the variable commonly used for slope. Hope this helped!

Lona read 40 books for the read-a-thon. She read 30% historical fiction and20% sports stories. The rest were mysteries. How many mysteries did lona read?

Answers

20 mysteries. Add 20% and 30% to get 50%. Then rewrite 50% as 50/100. Next multiply 50/100 by 40 to get 2,000/100.The last thing to do is simplify to get 20 and subtract 20 from 40 to get 20 mysteries.

Solve this inequality: 9h + 2 < –79.

Answers

The given expression of inequality can be solved as  h < -9.

What is linear inequality?

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The given inequality is as below,

9h + 2 < –79.

It can be solved as follows,

9h + 2 < –79

Subtract 2 from both sides to get,

9h + 2 - 2 < –79 - 2

⇒ 9h < -81

Divide by 9 on both sides as,

9h ÷ 9 < -81 ÷ 9

⇒ h < -9

Hence, the solution of the given inequality is h < -9.
