A line includes the points (4,1) and (8, 2). What is its equation in slope-intercept form?

blsea [12.9K]

Answer: y = 4x

Step-by-step explanation: Slope intercept form is y = mx + b where m is the slop and b is the x intercept

We can solve for slope using the given points

(2-1)/(8-4) = 1/4, thus m = 1/4

y = 1/4x +b

Now to solve for b, we can just plug in one of the points to see what makes b work

1 = 4*(1/4) + b

1 = 1 +b

b = 0

The expression x−y equals 0.7 if x and y have certain values. Evaluate the following expressions with the same values of x and y

Marina86 [1]

Answer:

-0.7

Step-by-step explanation:

$x-y=0.7$

You can choose any digits you wish for $x$ and $y$ but the difference must be 0.7. I chose 1.0 and 0.3.

$x=1\\y=0.3\\x-y=0.7\\\\y-x=\\0.3-1=\\-0.7$

Given the midpoint (1.5,1.5) and the endpoint (5,7) where is the other endpoint located

earnstyle [38]

The formula of a midpoint:

$M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)$

We have:

$M(1.5,\ 1.5)\to x_M=1.5,\ y_M=1.5\\A(5,\ 7)\to x_A=5,\ y_A=7$

Substitute

$\dfrac{5+x_B}{2}=1.5\qquad|\cdot2\\\\5+x_B=3\qquad|-5\\\\x_B=-2\\\\\dfrac{7+y_B}{2}=1.5\qquad|\cdot2\\\\7+y_B=3\qquad|-7\\\\y_B=-4$

<h3>Answer: (-2, -4)</h3>

NEEDED ASAP WILL MARK AS BRAINLIEST

adoni [48]

Explanation:

This might not be how you are supposed to do it but,

We can see the two triangles are similar because AA similarity.

We know that the sides are proportional so we can make:

$\frac{x+2}{x}=\frac{4}{3x-1}$

We get,

$3x^2+5x-2=4x\\3x^2+x-2\\(3x-2)(x+1)=0\\x=2/3, x=-1$

Because sides can't be negative, x = 2/3
