I just did the question on math watch.
Answer:

Step-by-step explanation:
Write down the problem;

Simplify

Convert so that the fractions have a common denominator; multiply the numerator and denominator of both fractions such that the denominators are equal;

Add the fractions;

Convert to mixed number;

If the number of pounds of chicken is represented by c, then the number of the pounds of beef is 12 - c. The equation that best represent the given conditions above based on the total amount that Jenny spent is,
1.9c + 4.3(12 - c) = 34.8
The answer is letter D.
First you need to put the equation into slope form which is y = mx + b
-3x + 2y = 2
2y = 3x + 2
y = 1.5x + 1
In this equation the y-intercept is 1 and the slope is 1.5 or 3/2.
To graph the line you can start at the y-intercept then move up 3 and to the right 2 or down 3 and to the left 2.
Three points are (2, 4) , (-2 ,-2), (4, 7).
