Slope = (y2 - y1) / (x2 - x1)
slope = (5 + 7)/(10 - 4) = 12/6 = 2

point slope form:
y - y1 = m(x - 1)
in this case:

If you use point (4,-7) then equation will be:
y -(- 7) = 2(x - 4)
y + 7 = 2(x - 4)

If you use point (10,5) then equation will be:
y - 5 = 2(x - 10)

Answer:
B. y - 5 = 2(x - 10)

Helppppp and explain pls and thankyouuu

Answer:

third option (7.5, 8)

this option (6, 5, -3)

Step-by-step explanation:

you eliminate one variant by expressing it through the other(s) until you have one equation with one variable.

that you solve, and then you go back to the other elimination expressions to calculate the others.

2x - y = 7

-2x + 3y = 9

since the terms with x are already so similar, we could now simply add both equations and solve that result :

2x + (-2x) -y + 3y = 7+9 = 16

0×x + 2y = 16

2y = 16

y = 8

2x - 8 = 7

2x = 15

x = 7.5

x - 2y - 3z = 5

x + 2y + 3z = 7

x + z = 3

the same trick by adding the first 2 equations

x + x -2y + 2y -3z + 3z = 5 + 7 = 12

2x + 0y + 0z = 12

2x = 12

x = 6

6 + z = 3

z = -3

and then

6 + 2y + 3(-3) = 7

6 + 2y - 9 = 7

2y - 3 = 7

2y = 10

y = 5

What is the equation of the line?

Oksi-84 [34.3K]

First find the slope of the line. Slope is defined as the change in y over the change in x.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Find two ordered pairs and plug them into the slope formula.

After looking at the graph, I found two points: (0, 1) and (4, 4)

$\frac{4 - 1}{4 - 0} = \frac{3}{4}$

Now find where the line intersects the y-axis.

After looking at the graph, I found out that the line intercepts the y-axis at
(0, 1)

Now build the slope-intercept equation.

General form: y = mx + b
Where m is the slope and b the y-intercept

So, the answer is y = 3/4m + 1

(6a + 5b + 4c) + (–6c + 15b) + (–8a)

kenny6666 [7]

Answer:

-2a + 20b - 2c

Step-by-step explanation:

(6a + 5b + 4c) + (–6c + 15b) + (–8a) = 6a + 5b + 4c - 6c + 15b - 8a

= 6a - 8a + 5b + 15b + 4c - 6c

= -2a + 20b - 2c

Kim drives 156 miles from rotherham to London.She has an average speed of 60 miles per hour.

kicyunya [14]

Currently, you would ask "How long does it take to get from Rotherham to London?" You would do 156/60, which would be 2.6 hours. 2.6 hours is 156 minutes (2 hours, 36 minutes).
9:36 is when Kim would reach London, so yes.
