What is the equation of a line that passes through the points (2,3) and (-6,1)

Mathematics

Answer:

y = 1/4 x + 5/2

Step-by-step explanation:

first we need to find the slope which is difference of the y's over difference of the x's. so (3-1)/(2-(-6)). ---> 2/8 ---> 1/4. the slope is 1/4.

pick one of the coordinates and plug in the y and x, solving for the y intercept. so:

3=1/4 * 2 + a

3=1/2 + a

a = 3 - 1/2

a = 5/2

so:

y = 1/4 x + 5/2

What is the area of the triangle?
alexandr402 [8]

Answer:

15/2

Step-by-step explanation:

Hello,

the area of a triangle is b*h/2

we can set BC as the base because AC is harder to calculate.

Then we draw an imaginary height.

There's no way to really explain, but the height would be 5 here, since 3 - -2 = 5

The base is 3

3*5/2 = 15/2

Thanks,

Math problem!!! Help needed 10 points !!!
My name is Ann [436]

ANSWER

Option D

EXPLANATION

The parent radical function is

f(x) =  \sqrt{x}

The transformed function is

g(x) = 2 \sqrt{x - 3}

This is a transformation of the form.

y = a \sqrt{x - k}

which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.

In this case a=2 and k=3,

there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.

The last choice is correct.

F(x) = 3x + 3; f(33)
never [62]
<span>f(x) = 3x + 3; f(33)

Please help !! ( will mark you brainliest )
Ad libitum [116K]

Recall that a relationship is a function ONLY IF for each input (x-) value there is exactly one corresponding y value. More than that? Then the relationship is not a function. That applies to the first and the third relations given here.

The second relationship is a function.
