Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3, -4).

Nesterboy [21]

1) Point-slope form

(y-y1)=m(x-x1)

m= - 3,

point (3,-4), so x1 = 3, y1 = - 4.

(y+4)= -3(x- 3)

2)Point-slope form

(y-y1)=m(x-x1)

m= - 3/4,

point (4,5), so x1 = 4, y1 = 5.

(y-5)= - 3/4(x-4)

What set of reflections and rotations would carry rectangle ABCD onto itself? Parallelogram formed by ordered pairs A at negativ

Hoochie [10]

Answer:

Option (4).

Step-by-step explanation:

Let's take the coordinates of point A for the set of reflections and rotations given in the options.

Option (1). Rotate 180° → A(-4, 1) becomes (4, -1)

Reflect over x-axis → (4, -1) becomes (4, 1)

Reflect over the line y = x → (4, 1) becomes A'(1, 4)

Therefore, point A will not overlap itself after the number of transformations given.

Option (2). Reflect across x-axis → A(-4, 1) will become (-4, -1)

Rotate 180° → (-4, -1) becomes (4, 1)

Reflect over the x-axis → (4, 1) becomes A'(4, -1)

Therefore, point A(-4, 1) doesn't overlap A'(4, -1).

Option (3). Rotate 180° → A(4, 1) becomes (-4, -1)

Reflect over the y-axis → (-4, -1) becomes (4, -1)

Reflected over y = x → (4, -1) becomes (-1, 4)

So the point A(4, 1) becomes A'(-1, 4) after the set of reflections,

Option (4). Reflect over the y axis → A(-4, 1) becomes (4, 1)

Reflect over the x-axis → (4, 1) becomes (4, -1)

Rotate 180° → (4, -1) becomes A'(-4, 1)

Therefore, point A will overlap itself following the set of transformations.

Identify the slope and y-intercept of the<br> line!

marta [7]

Slope of the line = $\frac{1}{2}$ .

y-intercept of the line = -7.

Solution:

General form of equation of a line:

y = mx + c

where m is the slope and c is the y-intercept of the line.

Equation of a line:

$$y=\frac{1}{2} x-7$

To compare this with general equation.

$$m=\frac{1}{2}$

$c=-7$

Slope of the line = $\frac{1}{2}$ .

y-intercept of the line = -7.

Please help me im only looking for real answers

GrogVix [38]

Answer: y=3/2x

Step-by-step explanation:

First, to find the equation, we can figure out that the cost depends on how many tickets are bought. We can use cost as our y and # of tickets as our x.

An equation in slope intercept form is as follows:

y=mx+b

To get our slope, we must figure out the relationship between the cost and the number of tickets, or the y and the x.

We can use the slope formula, $\frac{y2-y1}{x2-x1}$ , to find the slope, m.

$\frac{3-6}{2-4}$ = $\frac{3}{2}$

Thus, the slope of the equation is 3/2, making our final equation be y=3/2x.
