Answer:

x = 2

Step-by-step explanation:

From the data, we obtain the slope :

-1, 8 ; 3, - 4

Slope = Rise / run

Rise = y2 - y1 = (-4 - 8) = - 12

Run = x2 - x1 = (3 - (-1)) = 4

Slope, m = - 12 / 4 = - 3

Recall:

Equation of line :

y - y1 = m(x - x1)

y - 8 = - 3(x + 1)

y - 8 = - 3x - 3

y = - 3x - 3 + 8

y = - 3x + 5

Substituting y = - 3x + 5 into the equation 2x+4y= 0

2x + 4(-3x + 5) = 0

2x - 12x + 20 = 0

-10x = - 20

x = 2

tresset_1 [31]

Answer:

61 + n = 82

Step-by-step explanation:

So the total number of candy is 82. This is the sum of each type of candy, i.e. 18 + 24 + 19 + n. So we have

18 + 24 + 19 + n = 82

61   +    n            = 82

( if we solve the equation we get n = 82 - 61 = 21)

Hope it helps and if it does please mark me brainliest;)

What is the function rule for the line?
11Alexandr11 [23.1K]
So with these equations we need to find the y-intercept and the slope because:

y = mx+b

y = f(×)

b = y-intercept

m = slope (slope = rise/run, rise over run)

rise is y-axis
run is x-axis

The y-intercept is (0,-2)
So now we know that one of the answers must have -2 in it

b = -2

m= rise/run = -2/3

The answer is:

f(x) = - \frac{2 }{3 } x - 2
