First find the slope
(0+2)/(1-2) = 2/-1 = -2
Y = mx + b
Y = -2x + b
Plot in any point
-2 = -2(2) + b, b = 2
Solution: y = -2x + 2

one pound of grapes costs $1.55. which equation correctly shows a pair of equivalent ratios that can be used to find the cost of
Marat540 [252]

startfraction 1.55 over 1 endfraction is x = 1.55

<h3>What is ratio?</h3>

A ratio in mathematics shows how many times one number is included in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is identical to the ratio 4:3). (i.e., 8:6, which is identical to 4:3). The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7). (or 4:7). A ratio can have any number of values, such as counts of people or things or measures of length, weight, time, etc. In most cases, both numbers must be positive.

EXPLANATION:

Sadly, we are unable to view the list of equations from which you can choose. But if we assume that x Equals the cost of 3.5 kg of grapes, we can construct the following equation

1/1.55 = 3.5/x

x = 1.55

PRETTY PLEASE HELP?????? 1. John can spend up to $40 for gasoline and a carwash at a service station. The carwash will cost $6.0
galina1969 [7]
1. 4.5g + 6 < = 40
    4.5g < = 40 - 6
    4.5g < = 34
    g < = 34/4.5
    g < = 7.56
True statement : John can buy 7 gallons but not 8

2. 250 + 3b < = 800
    3b < = 800 - 250
    3b < = 550
    b < = 550/3
    b < = 183.33
True statement : The maximum number of new baseballs that can be purchased is 183

3. 3x + 6 > 15
    3x > 15 - 6
    3x > 9
     x > 9/3
     x > 3

4. 4x - 6 < 2x + 8
    4x - 2x < 8 + 6
     2x < 14
      x < 14/2
      x < 7

5. 3 - 2x > 9
    -2x > 9 - 3
    -2x > 6 ...when dividing by a negative, u flip the inequality sign
      x < -6/2
      x < -3
     True statement : - 2

7. 3x - 3 < -12         OR     -4x < = -32
    3x < -12 + 3                    x > = -32/-4
    3x < - 9                           x > = 8
      x < -9/3
      x < -3
answer : x < - 3 OR x > = 8

8. -7x + 9 < 72    AND   5x - 3 < = 7
    -7x < 72 - 9                5x < = 7 + 3
    -7x < 63                     5x < = 10
     x > -63/7                     x < = 10/5
     x > - 9                         x < = 2
answer : -9 < x < = 2
