Answer:

-4

Step-by-step explanation:

From (-1,1) to (0,-3) is a fall of 4 and a run of 1

therefore rise over run = -4/1 = -4

Slope Formula

$slope = m = \frac{rise}{run}=\frac{change~in~y}{change~in~x} = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} =$ -4

Hope this helps,

SHOW STEP BY STEP FOR BRAINLIEST

Nostrana [21]

Answer:

The y-coordinate of F is 8.

Step-by-step explanation:

The area of the large triangle = 1/2 * base * height.

From the given coordinates:

The base of the large triangle = x coordinate of C - x coordinate of A

= 11 - 3 = 8 units.

It's height = y coordinate of A = 12, so

Area of large triangle = 1/2 * 8 * 12 = 48 unit^2.

Using a similar calculation for the small triangle:

Base = 10 - 6 = 4 and height = k units.

So it's area = 1/2 * 4 * k = 2k unit^2.

So from given area of the shaded part:

48 - 2k = 32

-2k = -16

k = 8.

Carl bought 19 apples of 2 different varieties to make a pie.The total cost of the apple was $5.10.Granny Smith apples cost $0.2

disa [49]

For this case we propose a system of equations:

x: Let the variable representing the quantity of Granny Smith apples

y: Let the variable representing the number of Gala apples

According to the statement we have:

$x + y = 19\\0.25x + 0.30y = 5.10$

From the first equation we have to:

$x = 19-y$

replacing in the second equation:

$0.25 (19-y) + 0.30y = 5.10\\4.75-0.25y + 0.30y = 5.10\\4.75 + 0.05y = 5.10\\0.05y = 5.10-4.75\\0.05y = 0.35\\y = \frac {0.35} {0.05}\\y = 7$

So, Carl bought 7 Gala apples

On the other hand:

$x = 19-7 = 12$

So, Carl bought 12 Granny Smith apples

Answer:

Carl bought 7 Gala apples and 12 Granny Smith apples

Complete equation describing how X and Y are related.

den301095 [7]

Answer:

$2$

Step-by-step explanation:

Every time the x-value increases by 1, the y-value increases by 2. Therefore, the slope of the line must be equal to $2/1=\boxed{2}$ (rise/y-values over run/x-values). In slope-intercept form $y=mx+b$ , $m$ represents the slope of the line, $b$ represents the y-intercept, and $(x,y)$ represents any point the line passes through.

Since $m$ represents the slope of the line, the value of

While the question only asks for this value, it's good to note that the equation of the function is $y=2x+7$ (find 7 by substituting any ordered pair in the table with $m=2$ ).
