Answer:

y = 1/2x + 1

Step-by-step explanation:

The slope is the change in y over the change in x. The line goes down one and two left, making the slope 1/2.

The line crosses the y axis at positive 1 and that is the y-intercept.

Y_Kistochka [10]

The answer for this question is =
y = 1/2x+ 8

Work
y= mx +b:
y= 1/2x+b
x= -4
y=6
6=1/2(-4)+b
6=-2+b
b=8
y=1/2x+8

There is a bag with only red marbles and blue marbles. The probability of randomly choosing a red marble is 2 9 . There are 63 m

Tatiana [17]

The main idea is the number of marbles and the denominator of the probability. All you have to do is multiply the fraction by a fraction which is equal to 1 which makes the denominator equal to 63. We know 63 is a multiple of 9. 9 goes 7 times in 63 so we multiple the fraction $\frac{2}{9}$ with $\frac{7}{7}$ which gives, $\frac{2 * 7}{9 * 7}$ which when evaluated gives $\frac{14}{63}$ and the numerator is the number of red marbles in the bag. So there are 14 red marbles in the bag :D
