Answer:

You can use the scale factor to determine if a picture is an enlargement if the scale factor is greater than 1. If it is less than 1 like 0.9 then the picture would be a reduction because you would be multiplying the number by a number smaller than 1. Now if we have a scale factor greater than 1 let's say 3. Then the picture would be an enlargement because the number is greater than 1.

A line contains the points (4,5) and (3, -9). Write the equation of the line using point-slope form.
neonofarm [45]

Answer:

C

Step-by-step explanation:

original formula is: y - y1 = m (x - x1) ordinates= (x1, y1)

insert the a corresponding x and y coordinate:

y + 3 = -2 (x + 9)

Don't forget to change the signs depending on whether their positive or negative:

(3, -9) since 3 is positive but there is a minus in the formula it would be -3

since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)

Write the point-slope form of an equation of the line through the points (-7, 7) and (4, 1).
seraphim [82]

Answer:

Choice B. \displaystyle y - 7 = -\frac{6}{11} \, (x + 7).

Step-by-step explanation:

Start by finding the slope of this line. Let (x_1,\, y_1) and (x_2,\, y_2) represent two distinct points on a line on a Cartesian Plane. (That is, x_1 \ne x_2.) The slope of this line would be:

\displaystyle \frac{y_2 - y_1}{x_2 - x_1}.

For the line in this question:

  • x_1 = -7,
  • y_1 = 7;
  • x_2 = 4,
  • y_2 = 1.

Indeed, x_1 \ne x_2. The slope of this line would thus be \displaystyle \frac{1 - 7}{4 - (-7)}, which is equal to \displaystyle -\frac{6}{11}.

On a Cartesian Plane, the point-slope form of a line that has a slope of m and includes the point (x_0,\, y_0) can be written as:

y - y_0 = m\, (x - x_0).

(Note the minus signs in this form.)

For the line in this question, m = \displaystyle -\frac{6}{11}. There are two equivalent expressions for its point-slope form:

  • Using the first point, y - 7 = \displaystyle -\frac{6}{11}\, (x - (-7)). This equation is equivalent to y - 7 = \displaystyle -\frac{6}{11}\, (x + 7).
  • Using the second point, y - 1 = \displaystyle -\frac{6}{11}\, (x - 4).
