Answer:

point slope form: y-(-4)=-3(x-1)

Slope intercept form: y=-3x-3

Step-by-step explanation:

Point slope form formula: y-y1= m(x-x1)

(1,-4), (-1,3)

Slope formula x2-x1/ y2-y1

Plug in the information 3-(-4)/-1-1

Simplify: 6/-2 or -3

Use one of the coordinates for the equation: y-(-4)=-3(x-1)

I used the first coordinate.

Slope intercept form formula: y=mx+b

Slope=-3

Plug in information: y= -3x+b

To find b, plug in one of the coordinates.

-4=-1+b, subtract to isolate b

b=-3

Your equation: y=-3x-3

Hope this helps!

What is the area of a triangle with vertices at (-3 3) (-3,2) and (1,2)?
d1i1m1o1n [39]
This is a right triangle, so first find the distance between the two legs...

Points where the numbers are the same indicate a point that is on the same axis as the other

(-3, 3) and (-3, 2) have a distance of 1


(-3,2) and (1,2) have a distance of 4

The area formula for a triangle is 1/2bh and in this case 1/2(1)(4) = 2

The area is 2

the product of two whole numbers is 36 . what is the greatest possible sum that the number can have?​
ch4aika [34]

Whole numbers are positive numbers without decimals.  First, list all the whole number factors of 36:

1 and 36

2 and 18

3 and 12

4 and 9

6 and 6

Next, see which one of those pairs has the highest sum:

1+36=37

2+18=20

3+12=15

4+9=13

6+6=12

The greatest possible sum the numbers can have is 37.

Hope this helps!!

Domain and range of the inequality y<√x+3 +1
Margaret [11]

The domain of the given inequality is y>1.

<h3>What is Inequality?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Here, given inequality:

              y < \sqrt{x+3}+1

Related equation:

             y = \sqrt{x+3}+1

The equation defined as,

    x+3 > 0

    x > -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

    \sqrt{x+3} \geq 0

adding 1 on both sides, we get

  \sqrt{x+3} + 1 \geq  1

      y ≥ 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

Thus, the domain of the given inequality is y>1.
