Write he slope intercept form of the equation of the line described

Alik [6]3 years ago

Hello!

The equation for slope intercept form is y = mx + b, where m is the slope and b is the y intercept.

We can first find the slope. Perpendicular lines have slopes which are negative reciprocals of each other. This means that the slope of the line you're looking for would be the negative reciprocal of -2/9. The negative reciprocal of -2/9 is 9/2. Therefore, m = 9/2.

Substitute this into the equation. y = 9/2x + b. Now substitute in the point given and solve for b.

y = -4, x = -2

-4 = 9/2 (-2) + b

-4 = -9 + b

b = 5

Therefore, the final equation is y = 9/2x + 5.

Hope this helps!

One leg of an isosceles right triangle measures 5 inches. Rounded to the nearest tenth, what is the approximate length of
Firlakuza [10]

The length of the hypotenuse = 7.1 inch

Step-by-step explanation:

In an isosceles right angle triangle if one leg is 5 inch, another side along the right angle is 5 in

hypotenuse = \sqrt{side^{2} +base^{2} } ( by Pythagoras theorem)

= \sqrt{5^{2}+5^{2} }

= \sqrt{50}

= 7.07106781

= 7.1 inch (approx)

Simplify to create an equivalent expression. 8−4(−x+5) Choose 1 answer: A 4x−12 B −4x−12 C 4x+13 D 4x+5
Kaylis [27]

Answer:

A (4x-12)

Step-by-step explanation:

Still think of PEMDAS: 8-4(-x=5)

a) Multiply -4(-x + 5)

* -4(-x) = 4x (remember a neg x neg = pos)

* -4(5) = - 20

b) Now it reads = 8 +4x - 20

c) put all like terms together

* 8 - 20 = -12

Answer: A: Whole Number B:Integer and C: Rational are all correct.

For the question: In the figure, AB is divided into equal parts. The coordinates of point A are (2, 4), and the coordinates of point B are (10, 6). Match each pair of coordinates to the corresponding point on AB.

Answer:The coordinates of the point are (6 , 5).

For the question: Imani and Abedi drive to work. Imani drives 66 miles in 1.5 hours. Abedi drives 56 km in 1 hour 15 min. Work out the difference between their average speeds in km/h. 1 mile = 1.6 km

Answer:25.6 km/h

I couldn't help you on all of them, but I helped you on some. Hope this helps :D
