Write the equation of a line that passes through the points (-3, 7) and (3, 3).
egoroff_w [7]

Answer:

y = -2/3x + 5

Step-by-step explanation:

(-3, 7) and (3, 3)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(3 - 7) / (3 -(-3))

Simplify the parentheses.

= (3 - 7) / (3 + 3)

Simplify the fraction.

= (-4) / (6)

= -4/6

= -2/3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2/3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 3). Plug in the x and y values into the x and y of the standard equation.

3 = -2/3(3) + b

To find b, multiply the slope and the input of x(3)

3 = -2 + b

Now, add 2 to both sides to isolate b.

5 = b

Plug this into your standard equation.

y = -2/3x + 5

This is your equation.

Check this by plugging in the other point you have not checked yet (-3, 7).

y = -2/3x + 5

7= -2/3(-3) + 5

7 = 2 + 5

7 = 7

Your equation is correct.

Hope this helps!

The coordinates of the vertices of quadrilateral ABCD are A(-5, 1), B(-2,5), C(5, 3),
sladkih [1.3K]

Step-by-step explanation:

To calculate a slope, we need to apply: m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Applying formula to each slope:

m_{AB}=\frac{5-1}{-2-(-5)} = \frac{4}{3}  \\m_{BC}=\frac{3-5}{5-(-2)} =\frac{-2}{7}\\m_{CD}=\frac{-1-3}{2-5}=\frac{-4}{-3} =\frac{4}{3}

So, as you can see, there are equal pair of slopes, meaning that they are parallels, which<em> demonstrate that it's actually a quadrilateral figure.</em>

Xiaoming is making cookies. Each batch of cookies uses3 eggs. If Xiaoming has 20 eggs, and assuming he has enough of the other i
koban [17]

Answer:

6

Step-by-step explanation:

3(1)=3       3(2)=6          3(3)=9      3(4)=12     3(5)=15

3(6)=18     3(7)=21         3(8)=24

----------------------------------------------------

3(6)=18 is closest to 20

so the greatest number of batches Xiaoming can make is 6.
