Answer:

The equation of the line is y = -2x + 7

Step-by-step explanation:

* Lets study how to make an equation of the line from two point

- If the line passes through points (x1 , y1) and (x2 , y2)

- The form of the equation is y = mx + c, where m is the slope of the

 line and c is the y-intercept

- The rule of the slope is m = (y2 - y1)/(x2 - x1)

- The y-intercept means the line intersect the y-axis at point (0 ,c)

* Now lets solve the problem

∵ The line passes through points (-3 , 13) and (4 , -1)

- Let (-3 , 13) is (x1 , y1) and (4 , -1) is (x2 , y2)

∵ m = (y2 - y1)/(x2 - x1)

∴ m = (-1 - 13)/(4 - -3)

∴ m = (-14)/7 = -2

- Lets write the form of the equation

∵ y = mx + c ⇒ substitute the value of m

∴ y = -2x + c

- To find the value of c use one of the two points to substitute the

  values of x and y in the equation

∵ The line passes through (4 , -1)

∴ -1 = -2(4) + c

∴ -1 = -8 + c ⇒ add 8 to both sides

∴ -1 + 8 = -8 + 8 + c

∴ 7 = c

∴ y = -2x + 7

* The equation of the line is y = -2x + 7

Don’t really understand it someone help
stich3 [128]

Answer:

<em>n = 8 or n = −2</em> <em>is the correction solution.</em>

Step-by-step explanation:

As the absolute value equation is given:                                      

                                            | n−3 | = 5

We know either n − 3 = 5 or n − 3 = −5

                                               n − 3 = 5            (First Possibility)

                                          n − 3 + 3 = 5 + 3

                                                       n = 8

                                                n − 3 = -5            (Second Possibility)

                                                      n = -5 + 3

                                                      n = -2

                  <em> So, n = 8 or n = −2</em> <em>is the correction solution.</em>

Write the equation that represents the line that goes through the point (5, -7) and has slope m=-3
RUDIKE [14]

Answer:

<u>y = -3x + 8</u>

Step-by-step explanation:

<u>Given :-</u>

Point on line = (5, -7)

Slope (m) = -3

<u>To find :-</u>

Equation of line

<u>Solving :-</u>

Using point-slope form of equation,

y - y₁ = m(x - x₁)

y + 7 = -3(x - 5)

y + 7 = -3x + 15

<u>Solution :-</u>

<u>y = -3x + 8</u>
