Write an equation in slope-intercept form for the line that passes through (5,4) and (6,-1)
xenn [34]

Answer:

Y = -5x + 29

Step-by-step explanation:

The first step is finding the slope:

y2 - y1 / x2 - x1

-1 - 4 = -5

6 - 5 = 1

-5/1 = -5

Now to point slope form ( y - y1 = m (x - x1)

Let's use the point 5, 4.

y - 4 = -5 (x - 5)

Time to simplify to slope intercept form ( y = mx + b)!

1. distribute

y - 4 = -5x + 25

2. Add 4 to both sides, making y alone.

Y = -5x + 29

How do i solve this?
Andrews [41]

Answer:

F. 3 5/6

Step-by-step explanation:

3/5b - 1/2 = 1 4/5

Add 1/2 to both sides. To do this make the 4/5 have a common denominator of 10 by multiplying it by 2/2. Make 1/2 have a common den. of 10 by multiplying it by 5/5.

  • 4/5 * 2/2 = 8/10
  • 1/2 * 5/5 = 5/10

Now you can add.

3/5b = 1 13/10, which can be simplified to 2 3/10.

To isolate b, divide both sides by 3/5. This is the same as multiplying by 5/3 (reciprocal). First make 2 3/10 an improper fraction.

23/10 * 5/3 = 115/30

Simplified: 3 5/6

guajiro [1.7K]

Answer:

There are <u>72 inches</u> in 6 feet.

Step-by-step explanation:

Given:

There are 12 inches in 1 foot.

Jada is working on improving her vertical jump.

Currently, her standing reach is 6 feet from the ground.

Now, to find the inches in 6 feet.

Let the inches in 6 feet be x.

As given:

In 1 foot there are 12 inches.

<em>So, 1 foot is equivalent to 12 inches.</em>

<em>Thus, 6 feet is equivalent to </em>x<em />

Now, to find using cross multiplication method:

\frac{1}{12} =\frac{6}{x}

<em>By cross multiplying we get:</em>

x=72

So, the inches in 6 feet = 72.

Therefore, there are 72 inches in 6 feet.

Mei is writing a coordinate proof involving a right isosceles triangle. Mei places her triangle on the coordinate plane such tha
bulgar [2K]

Answer: (a,a)


Step-by-step explanation:

Given: A  right isosceles triangle which is placed on the coordinate plane such that one of the legs of the triangle lies along the x-axis and the other leg is parallel to the y-axis.

From the given figure one vertex is on origin(0,0) and second on x -axis as (a,0) .ii.e. one side of the triangle is on the x axis with length 'a' and the side parallel to the y axis should perpendicular to the x axis with length 'a'.(∵ two sides are equal in a right isosceles triangle)

So the coordinates should she assign to the third vertex of the right isosceles triangle is (a,a).[as the point lie above the point (a,0), so its x abscissa should be same]
