Write an equation in slope-intercept form for the following line:<br><br> (-14,1) and (13,-2)
alex41 [277]

Answer:

\large \boxed{y =  -  \frac{1}{9} x -  \frac{5}{9} }

Step-by-step explanation:

In order to find an equation of a line with two given ordered pairs. We have to find a slope first which we can do by using the formula below.

\large \boxed{m =  \frac{y_2 - y_1}{x_2 - x_1} }

m-term is defined as slope in y = mx+b form which is slope-intercept form.

Now we substitute these ordered pairs (x, y) in the formula.

\large{m =  \frac{1 - ( - 2)}{ -14 - 13} } \\  \large{m =  \frac{1 + 2}{ - 27} } \\  \large{m =  \frac{3}{ - 27}  =  -  \frac{1}{9} }

After we calculate for slope, we substitute m-value in slope-intercept form. The slope-intercept form is

\large \boxed{y = mx + b}

We already know m-value as we substitute it.

\large{y =  -  \frac{1}{9} x  + b}

We are not done yet because we need to find the b-term which is our y-intercept. (Note that m-term is slope while b-term is y-intercept)

We can find the y-intercept by substituting either (-14,1) or (13,-2) in the equation. I will be using (13,-2) to substitute in the equation.

\large{y = -  \frac{1}{9} x + b} \\  \large{ - 2 =  -  \frac{1}{9} (13) + b} \\  \large{ - 2 =  -  \frac{13}{9}  + b} \\  \large{ - 2 +  \frac{13}{9}  = b} \\  \large{ -  \frac{5}{9}  = b}

Finally, we know b-value. Then we substitute it in our equation.

\large{y =  -  \frac{1}{9} x + b} \\  \large{y =  -  \frac{1}{9} x -  \frac{5}{9} }

A rotation is a transformation where an object
prohojiy [21]

Rotation is a transformation where an object is rotated about a fixed point.

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

<em>Translation, reflection and rotation</em> are rigid transformations because they preserve the shape and size of the figure.

Rotation is a transformation where an object is rotated about a fixed point.

MrRa [10]

Answer:

140 miles

Step-by-step explanation:

1 times 20 (1 inch=20 miles)

2 times 20 (2 inches=40 miles)

3 times 20 (3 inches=60 miles)

4 times 20 (4 inches=80 miles)

5 times 20 (5 inches=100 miles)

6 times 20 (6 inches=120 miles)

7 times 20 (7 inches=140 miles)

Hope this helped!! :)

The vertical asymptote is x = ?<br>y=a/x-h +k​
gtnhenbr [62]

Answer:

x=a/(y-k)+h

Step-by-step explanation:

y-k=a/(x-h)

(y-k)(x-h)=a

xy-hy-kx+kh=a

xy-kx=a+hy-hk

x(y-k)=a+h(y-k)

x=a/(y-k)+h
