Answer:

y = x + 1

Step-by-step explanation:

Points (-8, -7) and (0, 1) are marked on the line. These can be used to find the slope of the line using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (1 -(-7))/(0 -(-8)) = 8/8 = 1

The y-intercept is the y-value where the line crosses the y-axis. That point is marked, and its y-value is 1.

Then the slope-intercept form of the equation for the line is ...

y = mx + b . . . . . . line with slope m and y-intercept b

y = 1x +1 . . . . . fill in the values for m and b

y = x +1 . . . . . the coefficient of x is understood to be 1

A bottle contains 30 fluid ounces of orange juice and 18 fluid ounces of pineapple juice. Which graph has a slope that best repr

mojhsa [17]

Answer:

option B. G

Step-by-step explanation:

Let

y ---->ounces of orange juice

x ---> ounces of pineapple juice

we know that

The ratio of orange juice to pineapple juice is equal to

$ratio=\frac{y}{x}$

substitute the given values

$ratio=\frac{30}{18}$

simplify

$ratio=\frac{5}{3}=1.67$

<u><em>Verify each graph</em></u>

Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

we have

$ratio=\frac{5}{3}$

that means

5 ounces of orange juice per 3 ounces of pineapple juice

Graph F

The slope is

$m=\frac{4}{6}=\frac{2}{3}=0.67$

Graph G

The slope is

$m=\frac{4}{2}=\frac{2}{1}=2$

Graph H

The slope is

$m=\frac{70}{6}=\frac{35}{3}=11.67$

Graph J

The slope is

$m=\frac{12}{10}=\frac{6}{5}=1.2$

The value of 2 is the value closest to 1.67

therefore

The graph that has a slope that best represents the ratio of orange juice to pineapple juice is Graph G
